Essay about Public Safety vs. Civil Rights - 1628 Words

Public Safety v. Civil Rights CJA 550 Crystal Shepherd March 7, 2011 The argument of public safety versus civil rights has always been at the forefront of many major political issues in the United States. Civil rights are the foundation of this country, and they protect it’s citizens. But with that, comes the protection of criminals, terrorists, and enemies of the state, and the freedom for these people to move and operate against American ideals. The slightest restrictions on civil rights increases the safety of the general public, enables law enforcement agencies to operate more fluidly, and increases the rate for crushing the opposition. The safety of the general population is far more important than the protection of the rights†¦show more content†¦Some of the countries and states still have the electric chair, firing range, and even the hanging squad. One of the states that still had the electric chair was Nebraska. Nebraska, the only state with the electric chair as the primary method of execution, determined on February 8, 2008 that it was cruel and unusual punishment under the states constitution, and the United States constitution. Prisoners are no longer electrocuted in Nebraska, and now the state has no method of execution. A survey of experts from the American Society of Criminology, the Academy of Criminal Justice Sciences, and the Law and Society Association showed that the overwhelming majority did not believe that the death penalty is a proven deterrent to homicide. (Radelet Akers, 1995) Gun Control: Amendment Violation or Public Safety Concern The NRA argues that the Second Amendment of the U. S. Constitution guarantees individuals the right to own and carry guns. They are concerned that federal regulations will continue to increase until owning a handgun will be difficult to achieve, infringing on their Constitutional rights. They also argue that if law-abiding citizens have guns, they are safer from criminals, bringing crime rates down.

A book critique team leadership in christian ministry using multiple gifts to build a unified vision bY kENNETH o. gANGEL free essay sample

â€Å"Team leadership is the exercise of one’s spiritual gifts under the call of God to serve a certain group of people in achieving the goals God has given them toward the end of glorifying Christ.† Author Kenneth O. Gangel states this in no uncertain terms in his book, Team Leadership in Christian Ministry: Using Multiple Gifts to Build a Unified Vision. This helps serve as foundational posts from which he tackles his points in the book. All else anchors on this definition of team leadership. It is the same in terms of the secular viewpoint where people are able to exercise their talents and abilities to the maximum, except of course, this one has the end goal of glorifying Christ. This paper delves into the different elements of team leadership and how one can move beyond his comfort zone into a most fulfilling exercise of leading with and through others. Gangel’s idea of team leadership Gangel’s idea of a â€Å"home team† best illustrates what he means and if done in a church set-up can be a very effective kind of leadership. Of course, essential in all these are committed men and women who fulfill the impulse to improve themselves and who determine the direction a mission will take, possessing a strong commitment to values. This is the factor that ultimately motivates people to stay despite various pressures. In the church set-up, for example, it is one thing to have a vision of touching the lives of young people. Such goal is noble and grand. But it is another thing to stay on course despite the tediousness of tasks, or to remain cool, calm and collected when people behave differently from what one had expected. As the complexity of the church ministry increases, coordination relies increasingly on the use of direct supervision with team leaders tasked to provide feedback and communication at all times. So, with increased organizational complexity comes an increased need to manage human activities. The leaders are challenged to meld the demands of the church and the needs of the individual workers into a functioning whole. What Gangle is saying is that real motivation catches internally, after the mission is clear. Peak performers draw productivity from deeper reserves that are inexhaustible – from the sources of motivation. One can tell people to value excellence. He can insist that they increase their productivity. He can emphasize the need for changing their behavior. He can attempt to train people and motivate them to upgrade their job skills and increase their effectiveness. But until an individual in the church ministry sees that leadership is one of servanthood, there is no real team leadership. Gangle maintains that efficient means of keeping people associated with the values and goals of an organization is by developing a culture that encourages people to focus on a higher purpose for their work. Values that support this kind of consistent operation include the idea that people are basically, good, rational and interested in achievement. Leaders that unify members believe that the individual has something to contribute to the church. The bottom line for church leaders who want to create a culture of success is to start with creating a positive environment. They need to bring in people whose values are in line with the organization’s culture, and continue to acknowledge success and involve the whole organization in maintaining an environment that allows people to enjoy working hard to meet the church’s goals (Newstrom Davis 2002). Functions of Team Leadership Gangel not only makes a sweeping statement about team leadership and its features, for it is all too easy to say that one leaves one’s comfort zone and work things out with others. He also provides a biblical foundation for this team leadership model that he elucidates in his book. He emphasizes that it is not dogmatic control or personality worship because that can easily crumble in the light of the true Gospel of Jesus Christ, which is one of humility. It has also no room for political power play for the entire team shares leadership even as there is a leader at the helm of it all. To solidify his statements, he gives examples of Biblical characters whose kind of leadership provide exemplary examples of deeds worth noting in his team leadership model. An example is Paul who gently encourages Christians in his writings. Another example is Barnabas who provides venues so that people are able to develop and enhance their own gifts. And the ultimate example of this team leadership is Jesus Christ who chooses not one or two disciples, but twelve willing and humble people with the spirit of servitude and humility. Shift in Leadership Philosophy Gangel emphasizes a shift in leadership philosophy citing George Weber’s observation that â€Å"historic-command-structure organization is dead.† (Gangel, p. 15). He further emphasizes that the leader of tomorrow according to Weber must be a tireless, inventive, observant, risk taking and ever-hopeful builder and enabler of management and leadership teams within and among the organization’s constituent parts.† Gangel shares this observation of Weber stating that he sees team leadership in a church set-up as one with a Biblical mandate to it. He then supports his ideas by reflecting on the importance of clear-cut ministry philosophy with specific objectives firmly anchored on the Word of God. Yet, he observes that there are a lot of churches where these elements are already absent and so he brings us back to the time when early church scholars analyzed the church. (p. 16). Gangel’s posits on the different kinds of leadership from the earliest times and he prepares the readers to grasp what he will elucidate in the next pages on the true role of a team leader. Gangel’s kind of leadership involves influencing others to act toward the attainment of a goal. It harnesses the collective energy of a group of people and directs that energy towards the completion of a common goal. Common experience teaches that there is no formula to ensure success in leadership. Many leadership theories have been developed over the years to prove common experience wrong. The leader’s function is to motivate subordinates and help them reach their highly valued objectives. This theory is a highly participatory process, where all members are encouraged to join in every phase of any endeavor. As mentioned, when people participate, they feel and are actually empowered in the process. Their confidence in themselves, as well as in the project, is increased by a participative leadership style. Moreover, with more participants, diversity of ideas abounds, and the undertaking tends to become more fruitful, creative and different. Empowerment becomes a positive end result as well. Leaders must be able to facilitate the motivation of others by providing them an inspiring example. Also, in team leadership, all members and leaders must know that they have to start from themselves, and from their conditions. Self-analysis, and self-critique, accompanied action,   yield better collaboration, relationships and results. Indeed, a leader is also a follower and sometimes it is important, even necessary, for the leader to listen to others, and follow them. What makes Gangel’s book unique is that it starts logically from the overall picture of the kind of leadership of churches today and in Part 2, provides the qualities of a Team Leader and the many roles he assumes in the process such as a group facilitator, a conflict manager, a motivator, a mentor and many more.

Eulogy for Western Culture Essays - Literature, Poetry, Eliot Family

Eulogy for Western Culture Essays - Literature, Poetry, Eliot Family Eulogy for Western Culture World War I brought about the most profound and impactful paradigm shift in Western culture since the Enlightenment, and Western culture still feels the ripples of its impact a century later. World War I was the deadliest war of its time in terms of both the number of casualties and the destruction of European cities and countryside. If the fatalities from the Spanish Flu, wh ich spread so widely as a direct result of the war, are included, WWI is the deadliest war the world has ever seen. Yet, o ut of this staggering loss came some hope. World War I accelerated the process of globalization that began in the 18 th Century , and this triggered an economic boom . However, t his new globalization , along with political mishaps at Versailles , set up the world for the Great Depression, World War II, and the Cold War. World War I sent the West into a new and chaotic world. Some found it exciting, while others found it horrifying. Ma ny lauded the e conomic and cultural boom of this post-war world; however , others mourned the straying from old traditions and values and felt that this cultural shift was a simple decline in morals. T.S. Eliot doubtlessly held the second opinion . In his 1922 poem The Waste L and , Eliot laments the decline of Western culture and intelligence and assigns the blame to people straying from tradition and religion to instead busy themselves with immoral activities, especially sex. However, Eliot also advises that there is hope for change if people will rectify their values. This essay will examine how Eliot uses The Waste Land to express both his disappointment and advice for Westerners after World War I by dissecting the symbolism infused in the poem . The Waste L and reflects the destruction and desolation of post-war Europe, both physically and culturally. In the poem, the waste land is physically desolate. Before one even begins reading, the title itself conjures an image of a broken land much like Europe's post-war landscape marred by trenches, bombs, and death. A lthough the physical devastation of Europe was staggering, the physical state waste land primarily serves as a metaphor for the state of Western culture : an intellectual and moral waste land. The primary features of the waste land are its dryness and pollution , and these represent the intellectual and moral decay of the West. The pollution of the waste land represents the disrespect that people were showing for their culture . T he land is filthy, and the nouveau-riche litter their houses with gaudy decor. The setting for part of the poem is London, and "brown fog," or smog from industrial waste, covers the city (70). Smog is a particularly apt symbol because it is completely encompassing. It hangs over a n entire city, or an entire cu lture. Wherever one looks, there is smog; wherever Eliot looks, there are magazines, dime novels, and movies. Similarly, light does not penetra te smog that is so thick that it appears to be brown. Refined culture and entertainment -like literature, plays, and symphoniescannot penetrate the smog' of pop culture. The famous Thames River that runs through London is also in a sorry state. It is so extraordinary for the Thames to be clean that it must be pointed out that "no empty bottles, sandwich papers, / [s]ilk handkerchiefs, cardboard boxes, [or ] cigarette ends" run float in it (175-176). Nevertheless, rats infest its bank s . Bodies of water are integral parts to civilization. Just as the Nile is synonymous with Egypt, the Thames is a symbol of London. If the Thames is polluted, London is polluted. Further, while yes, London is polluted with industrial emissions and litter, the grime primarily serves as a symbol for the pop culture that is polluting Western culture . This pollution is not necessarily ugly. The mansion in "A Game of Chess" is quite beautiful . A "candelabra," "jewels," "ivory," "marble," and "satin" decorate the interior ( 78-86) . However, the decor is ostentatious. It shows that the mansion's owners, the new wealth' of the West, do not have good taste.

Eleanor, Queen of Castile (1162 - 1214)

Eleanor, Queen of Castile (1162 - 1214) Eleanor Plantagenet, born in 1162,   was the wife of Alfonso VIII of Castile, daughter of Henry II of England and  Eleanor of Aquitaine, sister of kings and a queen; mother of several queens and a king. This Eleanor was the first of a long line of Eleanors of Castile. She was also known as  Eleanor Plantagenet, Eleanor of England, Eleanor of Castile, Leonora of Castile, and Leonor of Castile. She died on October 31st, 1214.   Early Life Eleanor was named for her mother, Eleanor of Aquitaine. As a daughter of Henry II of England, her marriage was arranged for political purposes. She was paired with King Alfonso VIII of Castile, betrothed in 1170 and married sometime before September 17, 1177, when she was fourteen. Her full siblings were William IX, Count of Poitiers; Henry the Young King; Matilda, Duchess of Saxony; Richard I of England; Geoffrey II, Duke of Brittany;  Joan of England, Queen of Sicily; and John of England. Her older half-siblings were  Marie of France  and  Alix of France Eleanor as Queen Eleanor was granted control in her marriage treaty of lands and towns so that her own power was nearly as much as her husbands. The marriage of Eleanor and Alfonso produced a number of children. Several sons who were, in turn, expected heirs of their father died in childhood. Their youngest child, Henry or Enrique, survived to succeed his father. Alfonso claimed Gascony as part of Eleanors dowry, invading the duchy in his wifes name in 1205, and abandoning the claim in 1208.    Eleanor wielded considerable power in her new position.   Ã‚  She was also a patron of many religious sites and institutions,  including Santa Maria la Real at Las Huelgas where many in her family became nuns.   She sponsored troubadours to court.  She helped arrange the marriage of their daughter  Berenguela  (or Berengaria) to Leons king. Another daughter, Urraca, was married to the future king of Portugal, Alfonso II; a third daughter, Blanche or Blanca, was married to the future King Louis VIII of France; a fourth daughter, Leonor, married the king of Aragon (though their marriage was later dissolved by the church). Other daughters included Mafalda who married her sister Berenguelas stepson and Constanza who became an  Abbess. Her husband appointed her as ruler with their son upon his death, and also appointed her executor of his estate.   Death Although Eleanor thus became the regent for her son Enrique on her husbands death, in 1214 when Enrique was only ten, Eleanors grief was so great that her daughter Berenguela had to handle the burial of Alfonso. Eleanor died on October 31st, 1214, less than a month after Alfonsos death, leaving Berenguela as her brothers regent. Enrique died at age 13, killed by a falling roof tile. Eleanor was the mother of eleven children, but only six survived her: Berenguela  (1180 - 1246) - she married Conrad II of Swabia but the marriage contract was annulled. She married Alfonso IX of Leon, but that marriage was dissolved on grounds of consanguinity.   She became regent for her brother Enrique (Henry) I, and became Queen of Castile in her own right when he died in 1217. She abdicated right after that, and her son Ferdinand III of Castile brought together Castile and Leon.Sancho (1181 - 1181) - briefly heir to Castile, died at three monthsSancha (1182 - 1185)Enrique (1184 - 1184?) - heir during his very short life - there is some doubt that this child existed.Urraca - Urraca of Castile, Queen of Portugal (1187 - 1220), married to Afonso II of Portugal.Blanca -  Blanche of Castile, Queen of France (1188 - 1252), married the future Louis VIII of France, crowned Queen in 1223.

Big Data Executive Briefs Assignment Example | Topics and Well Written Essays - 3250 words

Big Data Executive Briefs - Assignment Example However, it can be said that the lifeline of business organizations all over the world is to cater to demand of the consumers and customers, and hence the customers become the life line of the organizations and businesses. With the increase in competition in the market place, the companies are finding it tough to gain competitive advantage over their rivals, who are targeting the same group of consumers with similar product offerings. The application of Big Data technology helps the companies in a major way in the process of accumulating and analyzing large amounts of data in real time scenario by building various kinds of predictive models that helps the companies to understand the trends and patterns of the multiple variables that might affect the prospects of the business. Talking about this particular company, it has been assumed that the company has mainly product based offerings in its portfolio. Highlighting in these lines, it can be said that because of the company’s g lobal presences in more than 18 countries around the world, which comprises of markets like Asia Pacific, the western and Latin American markets. Hence it can be easily mentioned that the company’s products are often exposed to consumers all around the globe, however, under a different brand and product portfolio. The product portfolio mostly comprises of fast moving consumer goods which are non perishable in the short term. However, it is of utmost importance to mention the fact that the product portfolio for various countries are variable in terms of market to market and region to region, as the product needs to be marketed in order to cater to the needs of the customers of that particular market. So, the application and extent to which the big data can be applied in this product based global company is tremendously wide. In more specific terms, the big data if applied in the process of mining information from the company’s social media marketing forums will result i n the gaining of significant needs and wants of the consumers, which are highly different in nature in regards to the location and region of the market. The implementation of the big data will also benefit the company in the process of increasing automation in the process of supply chain and thereby increasing the efficiency of product deliveries and potentially removing the option of stock outs of fast moving and high selling consumer demanded products. The implementation of the big data will also provide significant improvement in the reduction of lead time and thereby raising the productivity range and scales. On a note of conclusion, it can be said that the company will gain a lot of advantages if they are successful in the implementation of Big Data. Executive Briefing TO: Senior Company Executive FROM: Manager DATE: 11/21/12 SUBJECT: Need for Implementing Big Data in the Business Context The 21st century is the era of globalization.

About horror movies Essay Example | Topics and Well Written Essays - 1000 words

About horror movies - Essay Example The kind of character they portray in these movies is mostly driven by their ambitions in life. Unlike men who become comfortable with their statuses quickly, women are doing whatever they can to either maintain their facial looks or get the basic human wants (Wada-Marciano 12). A lady like Mrs. Li, for example, goes adopts a behavior of eating dumplings prepared from fetus for the sake of her looks and rejuvenating his husbands love Dumplings (Chan,2004). Greed also contributes to their characters in these horror movies because some of the females are conducting merciless killings just for food. In Onibaba film, we see two women killing soldiers, taking their armor and trading them for delicious meals. Such an action portrays greed because one has to sacrifice life of another for a single meal. Onibaba(Shindo,1964). Ambition and greed are portrayed more horrifying in female than in men.

Strong Women of Shakespeares Othello :: GCSE English Literature Coursework

Strong Women of Othello  Ã‚   William Shakespeare often described the women in his plays as being strong, confident individuals, much different from the stereotypical roles of the time period in which he lived. In Much Ado about Nothing, the main character____(look up) ---{describe role}. Similarly, in Macbeth, {discuss role of Lady Macbeth} The women of Othello also displayed characteristics of strong, modern women. .... From the beginning of the play, we see that Desdemona is a courageous and decisive woman who pursues Othello, falling in love with his intrigued stories of adventure, seeing "Othello's visage in his mind, and to his honors and valiant parts..." refusing the attempts of other suitors such as Roderigo. We become aware of Desdemona's determination when she marries Othello, despite accusations from Iago that she is under a spell and is deceiving her father. When her fiancà © is accused of bewitching her, she immediately defends her love for him. "And so much Duty as my mother showed to you, preferring you before her father, so much that I may profess due to the Moor my lord". Like many of Shakespeare's other female characters, Desdemona does not embody the stereotypical role of sixteenth century women. When Shakespeare wrote Othello, women had few rights and little power in society. They had virtually no say in arranging their own marriages, and were expected to marry a suitor chosen by their father. Desdemona, however, despite proposals from various suitors and public discouragement, continues her pursuit of Othello, and marries him. Although she is "†¦bound [to her father] for life and education†¦" , she affirms her belief that she belongs with Othello, and has such great love for him, so much that "a heave interim shall support his absence" . Soon after their elopement, envious Iago convinces Othello that Desdemona has been unfaithful to him. Othello becomes enraged cursing Desdemona as a whore. When Othello questions her, we again see her strong sense of devotion, pleading for his trust rather than vehemently defending herself. "I hope my noble lord esteems me honest†¦ Alas, what ignorant sin have I committed?" However, her faith in Othello is so strong that it undermines her "modern", prideful characteristics. Consequently, Desdemona is really not as strong and educated as originally perceived, for she continues to attempt to maintain Othello's trust, despite his incredibly harsh accusations. Although her arguments remain strong, the weakness in her character emerges, for she cannot see the monster that her husband is becoming, and failing to realize that he trusts Iago, a man who is extremely competitive with him, over his very wife's word.

Country Analysis – Myanmar

Myanmar is a resource-rich country and also known as the Asian rice bowl suffers from pervasive government controls, inefficient economic policies, corruption, and rural poverty. The economy suffers from serious macroeconomic imbalances including unpredictable inflation, fiscal deficits, multiple official exchange rates that overvalue the Burmese kyat, and unreliable statistics. In trade activity, Myanmar’s main imports are fabric petroleum products and crude oil, fertilizers, plastics, machinery, transport equipment food products and also construction materials. The major exports of Myanmar are natural gas, wood products, pulses and beans, fish, rice, clothing and jade and gems. On July 2012, the population in Myanmar is said to be 54,584650 people. Several considerations were made in counting and estimating the population including the effects of excess mortality due to AIDS. This can result in lower life expectancy, higher infant mortality, higher death rates, lower population growth rates, and changes in the distribution of population by age and sex than would otherwise be expected. Most people live in the 40,000-odd villages of the country, while the majority of the urban population resides in the capital city of Rangoon. Among the population engaged in agriculture, 37 percent of the people do not have any land or livestock. Poverty and misery have increased in the past 3 decades. It is estimated in the CIA World Factbook that in1997 23 percent of the Burmese population had incomes that placed them below the poverty line. PRICE STABILITY Inflation is the general increase in the level of price. Each and every country’s government has their own targets for the inflation rate in order to achieve price stability. It is impossible for a certain country to achieve zero level of inflation so an average of 2%-3% inflation is already good enough. The main indicator of price stability is the Consumer Price Index (CPI) which measures the degree of change in price as a whole. Figure 1. 0 The Percentage of Inflation in Myanmar Figure 1. 0 shows the graph of the inflation rate of Myanmar from 2007 to 2011. The year before 2007 shows a very high level of inflation in Myanmar which is around 35%. During that time, Myanmar’s economy is at the peak level. The export of Myanmar at that time was at the highest. The increase in the exports of rice and agricultural product caused demand pull inflation. This is because export is one of the components of the aggregate demand (AD). The high export rate causes the income of the local citizen becomes higher. A high income results in the increase in consumption. The increase in export and consumption which both are the component of AD causes demand pull inflation. To get a clearer view, refer to the graph below. In the contemporary, both of this component is also injection in the economy and causes the injection to become more than leakage. This creates a multiplier effect thus expands Myanmar’s economy. Figure 1. 1 Demand-pull Inflation In the year 2007, the basic commodity prices rose from 30 to 60 percent. At this particular time, the workers demand for more wages. The cost of production will increase thus shifting the short run aggregate supply (SRAS) to the left. This causes cost push inflation to the economy of Myanmar. But instead showing the increase in inflation level, the graph shows a slight inclination in the inflation rate. This is because the government implemented a contractionary policy to Myanmar’s economy. To the worst, the Cyclone Nargis hit Myanmar and this causes a negative growth of inflation to happen at a very high rate. Due to the disaster that happened, the government spending had to be focused on the welfare of the estimated 2. 4 million homeless victims. The money that should be invested on other things had been used for the recovery from the disaster. Meanwhile, Myanmar kept on exporting the rice in order to gain more profit without considering the number of seed that is reduced due to the destruction caused by the cyclone. This causes the production of rice and other agricultural product to be reduced in a great amount due to the disaster that happened. Besides, the length of production factor also will result on a huge shortage of food supply. This unknowingly converts Myanmar from a net rice exporter to importer. The higher amount of import than the export and added with the decrease in investment, also the government spending causes a shift in the AD to the left and results a decrease in the rate of inflation at a dramatic rate. Figure 1. 2 The year 2009-2011shows an increasing trend of inflation in Myanmar. This is when Myanmar enters the recovery phase of its economy. Probably during this phase Myanmar had already recovered from the cyclone and starts to increase their economic activity. More people will get employed and the consumption will increase. At the same time the government also spends a lot to bring back the economy of their country. This will shift the AD to the right thus increasing back the inflation rate. Figure 1. 3 FULL EMPLOYMENT Full employment means that every person in the labor force gets employed. It has become a significant objective for a country because it is closely related to the efficiency in resource allocation and also in achieving non-accelerating inflationary rate of unemployment (NAIRU). Both efficiency in resource allocation and the NAIRU are important to achieve a stable economy. Figure 2. 0 The Unemployment Rate in Myanmar The unemployment rate of Myanmar peaked at the year 2008. This is probably because the Nargis cyclone that hit Myanmar during that year causes death and destruction. The destruction also includes the farms and fields where most of Myanmar citizen works. This is called seasonal unemployment. Furthermore, during the financial crisis, the lack of import demand from other country causes many shutting down of shops and factories such as clothing factories, gemstone polishing and carving workshops, rubber factories and also the magazine and the publishing house. As a result, during that period of time, crimes such as theft and prostitution rate were seemed starting to rise. From 2008-2011, the rate of unemployment shows a decreasing trend. This is probably because of the agricultural sector that already recovered after the disaster that happened had opened a lot of job opportunities. In addition, an economic reform also had been made and training programs also were conducted such as the market opening policy. This increases the availability for the people in the labor force to get employed. The long run aggregate supply (LRAS) curve will shift to the right due to the changes in the government policy and also the education and training that have been made. Figure2. 1 Shift of Long-run Aggregate Supply In Myanmar, the participation of woman in the work force is still low and does not show any significant change in the labor participation which is majority participated by males. This is due to the trend in Myanmar where only male works while the female stays at home. ECONOMIC GROWTH Reviewing back to the economic problem, wants are unlimited but resources are scares. The objective of the economy is to solve this problem. So, economic growth is very important in order to satisfy more wants. Of course, there are several special consideration placed on the economic growth. One of them is the limitation of usage of resources for the future generation to use. Figure 3. 0 Myanmar GDP by-year Chart Overall, the economic growth of Myanmar on 2007-2011 shows an increasing trend. The year 2007-2008 shows the drop in economic growth and afterwards, the years after that show recovery. The world economy crisis that happened in the year 2008 really gave a huge impact on Myanmar economy because Myanmar is highly dependent on trading activities. The GDP of Myanmar that decreases to 1. 2% was not only caused by the economic crisis but also because of the Nargis cyclone that hit Myanmar in middle 2008. The â€Å"Lehman shock† that happened which causes a huge bankruptcy at Japan which is one of the main importer from Myanmar in the same year really affected the GDP of Myanmar. This results a decrease in economic growth of Myanmar due to the decreased size of natural resources caused by the Nargis cyclone, the uncontrolled inflation rate which is also relatively high in 2008 and also the political condition that was not so stable at that particular time. However, Myanmar shows an increased economic growth trend the year afterwards which is from 1. 2% to 5. 6%. This is because the export in Myanmar increases during these years. Due to some political tension, Korea increased their import share towards Myanmar and it became the third largest importer after Japan and Germany. As a result the combined export share for Korea and Japan reached 51. 5% and this trend seems to have become stronger in 2010. For the next year, it kept on growing on a steady rate due to no serious problem occurred. EXTERNAL BALANCE An economy that practices import and export is known as the open economic system. This means there are money going out and also coming in into a certain country. External balance means a balance between money inflow and outflow resulting from a country’s transactions with the rest of the world. It is a record of a country’s transaction in goods, services and assets with the rest of the world. There are three components of external balance which are the current account deficit as a percentage of GDP, net foreign debt as a percentage of GDP and the exchange rate. It is one of the macroeconomic objectives and its target is to achieve enough inflow from foreign country to buy imports and also being able to meet its financial obligation to other country. Current account deficit as a percentage of GDP. The current account measures the inflows and outflows of a country. It is divided to two categories which are the current flows and also the capital flows. The current flow consist of the export and the receipts of income payment as the inflow and the import and the income paid to overseas as the outflow. For the capital flows, the inflow is the foreign investment and the borrowing. The outflows are loan repayment and investment made overseas. Figure 4. 0 Current Account Balance in Myanmar The figure above shows the current account balance of Myanmar as a percentage of GDP. Over the years, it shows a decreasing trend from 2007-2011. However in 2009, it shows a sharp increase until 2010 and it falls back. It is certainly not highly affected by the export and import because referring to the graph below (graph 4. 1 and 4. 2) there is not much difference in the export and imports around these five years. The low value of the current account balance is due to Myanmar’s spending to meet its debt from other country. Graph 4. 3 shows the amount of Myanmar’s debt with other foreign country. Figure 4. 1 Exports of Myanmar Figure 4. 2 Imports of Myanmar Figure 4. 3 External Debt of Myanmar Exchange rate The value of a certain currency indicates how well a certain country is able to manage the financial inflow and outflow. A stable exchange rate indicates that the economy of a country is healthy and promotes investor to see that the country’s production is a worthwhile investment. The factors affecting the currency are highly related to the supply and demand for the currency. Figure 4. 4 The Graph of Supply and Demand for Currency In Myanmar, of course fluctuations of the Burmese Kyat (BK) happen from time to time. The exchange rate for BK is the price or value of one BK expressed in terms of foreign currency. The figure below shows the fluctuating BK throughout the five years period. Figure 4. 5 Myanmar Official Exchange Rate per US($) Over the five years the exchange rate of Myanmar shows a decreasing trend. A great depreciate if BK in the year 2007-2008 is due to the high inflation rate. The increase of the commodity prices decreases Myanmar’s export. Being a country that is very dependent on trading business, the decrease in the demand for Myanmar’s currency causes the AD shifts at a great amount to the left thus depreciating the currency. The depreciating of the currency will probably cause the current account deficit (CAD) of Myanmar to worsen. On the contemporary, the unemployment gap will also become bigger indicating the increasing in the unemployment rate. Figure 4. 5 In the year 2008-2009, Myanmar’s currency shows appreciation. This is due to the rate of inflation in Myanmar that is relatively low at the particular time. The low inflation means the price of local product is cheaper. The cheaper local product will make the local product price to be internationally competitive thus increases the export. The increase in demand for Myanmar’s currency will shift the AD to the right thus appreciate Myanmar’s exchange rate. People will also starting to get employed as the unemployment gap has become smaller. The CAD will expected to improve. Prospect Based on all analysis done, I estimated that Myanmar economic growth would continue growing if the government is very aware and carefully observing the fluctuating rate of inflation. The government must know the right time to implement whether a cotractionary or expansionary policy at the right time. For the full employment, it is the responsibility of the government to distribute and if necessary provide training for the population in order to achieve the full employment target. New rules and regulation and also policy must be implemented so that hard core unemployment, frictional unemployment, hidden unemployment and all other types of unemployment could be reduced. The economic growth of Myanmar is now in quite good position. However, it is unpredictable for something unwanted to happen such as global recession, increase in commodity price and natural disaster. So, economist and the government must take a serious consideration on planning a preparation for the economy to face unwanted situations to happen. For the exchange rate, it is better for Myanmar to maintain the value of Burmese kyat than trying to appreciate or depreciate it due to certain circumstances such as a cold diplomatic relationship with other countries and the unstable political condition inside the country itself. If any action is taken it is worried that a riot or the hampering of foreign investment from other country would happen. However, Myanmar should broaden their vision and observing how other country’s economy works. This is in order for Myanmar to improve its economy and foster a harmonious relationship with other countries abroad. If this could be achieved and be done, it is not impossible for Myanmar to leap up to the first rank in the world for the most high income country but with a low rate of inflation. Conclusion To wrap up, it is quite hard to say whether Myanmar have achieved or not achieved even any of the macroeconomics objectives. Although the economic growth and price stability keeps on fluctuating due to unwanted and also uncontrollable events, Myanmar still manage to overcome the problem or crisis even though still consumes a huge amount of time.

Hard Skills Vs. Soft Skills Essay

Introduction One million dollar question, which project and human resource management have asked for several years while doing recruitment, is whether do recruit individual endowed with hard skills or soft skills. This leads to asking the quest that between the two is the most important for an organization. Hard skills can be defined as technical know how or specific abilities that relate to the core business that an organization does to networking, machine operations among others. Soft skills, on the other hand, are subjective and undefined (Peggy, 2007).   It mostly deals with issues like communication, problem-solving, and conflict resolution among others. However, everybody agrees that both skills are necessary for the success of an organization, which between the two is most crucial? The crucial character of a manager is the ability to be flexible, a manager who can understand organization process, tools and techniques being utilized within the organization. Managers should be able to adapt to all types of organization and project process and have technical know-how on running team operation. This characteristic emphasizes on the soft skills and portrays technical skills as added advantage (Peggy, 2007) Managers spent most of their time almost 90% communicating, solving problems, negotiating planning among others. These are mostly soft skills that are being put to use. One can, therefore, argue that although both skills are essential, soft skills are being required in a higher percentage to help in coordinating hard skills for an organization success. Peggy (2007) states that whenever one wants to stay competitive and ahead of the game, one need to keep his or her hard skills sharp. However, for one to succeed faster, he needs to keep his soft skills updated. Therefore, in conclusion, soft skills always precede hard skills for an average person and training institution should ensure more soft skills in their employees. Motivation is one of the key elements for the performance of organization employees, as individuals who are highly motivated performs more than individuals who are not highly motivated. The motivation factors come from soft skills which when combined with hard skills then individuals can be in a position to achieve or reach self actualization. All employers needs employees who could deliver assignments in time and factor of time management plays very important aspect of project success. It also brings the idea of planning within organization which is an aspect of soft skills. Therefore we can conclude that even if one possess greater aspect of hard skills, without elements of soft skills the project can not be successful and always hard skills plays second place to soft skills. Good leadership calls for effective communication and without effective communication, project cannot pick off and starts operating smoothly, most researchers have argued that one with soft skills can assembly individuals with technical know-how and operates organization smoothly while individuals with only technical know-how could not manage an organization. This supports the arguments that human beings in terms of labour are the most valuable asset of an organization and if well managed then the organization will realize success. Hence soft skills are superior to hard skills. Reference Peggy K. (2007) THE HARD TRUTH ABOUT SOFT SKILLS: WORKPLACE LESSONS SMART PEOPLE WISH THEY’D LEARNED SOONER by.   Klaus & Associates, Inc.

The Magic LinkedIn® Formula

The Magic LinkedIn ® Formula My e-book, How to Write a KILLER LinkedIn ® Profile, enumerates 18 â€Å"Mistakes to Avoid† as well as 7 â€Å"Bonus Tips.† That’s a total of 25 items that I think are important for every LinkedIn ® user to understand and implement (actually more than 25, since many of the chapters have subpoints as well). Nevertheless, on Wednesday I will be giving a presentation at American Family Insurance’s DreamBank on â€Å"Top Five LinkedIn ® Mistakes.† Not 25, but 5. It’s not easy to choose the top five, but I managed to do it. Not only that, but I even narrowed it down to three general categories. I call this my â€Å"Magic LinkedIn ® Formula† and even if you’re unable to attend my presentation live on Wednesday, you can benefit from the formula. Success on LinkedIn ® comes down to what I have dubbed the â€Å"3 Ls† (not to be confused with the class of students in their third year of law school): Locatability Likeability ALiveness 1. Locatability If no one finds you on LinkedIn ®, there’s not much point in having a profile. Unless you are in a rare situation where you prefer not to appear in LinkedIn ® searches, easy locatability means you will get in front of the people searching for someone like you. For job seekers and business owners, being found by a target audience is one big key to success. Increasing your locatability entails two main actions: 1) putting the right keywords in the right places, and 2) growing your network aggressively and appropriately to at least 500 connections. A combination of well-placed keywords and a robust network is a winning LinkedIn ® strategy. 2. Likeability Just because someone finds you on LinkedIn ® doesn’t mean that person will contact you. If your profile is sloppy, incomplete, unfocused, or off target, you will probably be skipped over for someone with a better presentation. If, however, people like what they see, they will be more likely to request a connection or conversation. Likeability means sounding like a human being and not a robot; listing accomplishments without bragging; having an attractive photo and format; and putting your personality onto the page. The more you distinguish yourself as unique, the more you will encourage valuable interaction. 3. ALiveness I like to say that having a LinkedIn ® profile is like having a gym membership. You only get value from it if you do the work! Sitting on your butt will not get you 6-pack abs †¦ or a new client or job through LinkedIn ®. Aliveness on LinkedIn ® includes but is not limited to updating your profile, participating in groups, sharing valuable information, engaging in discussions, and taking relationships off line to the phone or even a coffee shop! That’s my Magic LinkedIn ® Formula: Locatability, Likeability and ALiveness! Are you using it? If you already are doing everything listed above, great- you are a power LinkedIn ® user. In that case, I recommend that you dive more deeply into How to Write a KILLER LinkedIn ® Profile for the fine points that will bring your LinkedIn ® success up even another level. I’ll have time for QA at my DreamBank presentation on Wednesday, and you get to participate too. What burning questions can I answer about my Magic LinkedIn ® Formula and your LinkedIn ® profile challenges?

Ice Lab Report Example | Topics and Well Written Essays - 500 words

Ice - Lab Report Example We kept the bottles in hot water until we heard the ice crack and it slid from the bottle. When ice slid from each bottle we immediately measured the height and diameter of each ice piece. Then we placed each piece of ice on a wire grate and noted which piece of ice had come from which bottle. We placed the wire grate with pieces of ice on it away from the wind and waited for the ice to melt and noted the time with the stop watch. Meanwhile we calculated the surface area of the cylindrical ice pieces using the formula 2rh + 2r2 ; where r is the radius and h is the height of each piece of ice. We have used the formula of a cylinder to find the surface area of all pieces of ice because all pieces of ice frozen in different medicinal bottles had assumed almost the same cylindrical shape but they all had different diameters. We then repeated the whole experiment three times using the same medicine bottles and noted the time taken for ice pieces to melt in each trial as follows Our experiment proved that the shape of a piece of ice affects its melting time. As can be seen in the table the greater the surface area of a piece of ice the smaller it's melting time.

Discussion The head of the senate is the United States Vice President and shall have no vote unless there is an equal division (James 36). The senate chose the other officers including a head pro tempore, when the vice leader is absent, or when exercising the Office of the President of the United States. The sole power of the Senate is to try all the prosecutions. During this sitting, they should be on pledge or affirmation, and when there is a trial on the United States President, the presiding officer is the Chief Justice.

Natural Recycling of Aggregate

Natural Recycling of Aggregate Introduction For many years peoples have been trying to keep the environmental clean and mention the natural balance of life. The scientific studies provide us the information and methods to achieve these objectives and the recycling of waste and by product materials represent the main role in these studies [1-4]. As a result of reconstruction of existing buildings and pavements, wars and natural disasters such as earthquakes the amount of construction and demolition materials are increasing every year. At the same time approval of additional facilities for waste disposal or treatment are become more difficult to obtain. Furthermore increasing restrictive environmental regulations have made waste disposal more difficult and expensive. Also the available natural aggregate in some countries decreases and may be become insufficient for the construction projects in these countries in the future [5]. So, the reuse of construction and demolition materials in construction has benefits not only in reducing the amount of materials requiring disposal but also can provide construction materials with significant saving of the original materials. According to the third Building Waste Monitoring Report [6], there is an increase in the recorded amount of building waste in the sectors of the building debris, road scarification and building site waste. It has arisen in Germany by 11.5 million tons, from 77.1 million tons in the period 1997/1998 to 88.6 million tons in the period 1999/2000. According to Rahlwes and Schmidt [7, 8], for concrete only, the annual crushed concrete quantity in west Germany only is about 30 million tones and in the European Union is approximately 130 million ton. Due to intensive building activities in the last decades, these amounts are expected to considerably increase after the year 2000. The properties of recycled coarse aggregate with a grain size above 4 mm and its reuse in concrete production and pavements construction have been evaluated and described in many. It has been estimated that approximately 50 million tons of concrete are currently demolished each year in the European Economic Communities [1], Equivalent figures are 60 million tons in the United States ([2], [3]), and in Japan [12] the total quantity of concrete debris available for recycling on some scale is about 10 to 12 million tons. Very little demolished concrete is currently recycled or reused anywhere in the world. The small quantity which is recovered is mainly reused as unstabilized base or subbase in highway construction. The rest is dumped or disposed of as fill. For Environmental and other reasons the number of readily accessible disposal sites around major cities in the world has decreased in recent years. Both disposals volume and maximum sizes of wastes have been restricted. In Japan disposal charges from USD 3 to 10 per ton are not uncommon. Moreover, distances between demolition sites and disposal areas have become larger and transportation costs higher. At the same time critical shortages of good natural aggregate is developing in many urban areas, and distances between deposits of natural material and sites of new construction have grown larger, and transportation costs have become correspondingly higher, It is estimated that between now and year 2,000, three times more demolished concrete will be generated each year than is today. For these reasons it can be foreseen that demolition contractors will come under considerable economic and other pressure to process demolished concrete for reuse as unscreened gravel, base and subbase materials, aggregates for production of new concrete or for other useful purposes. Large-scale recycling of demolished concrete will contribute not only to the solution of a growing waste disposal problem. It will also help to conserve natural resources of sand and gravel and to secure future supply of reasonably priced aggregates for building and road construction purposes within large urban areas of the world. Applications of Recycled Aggregate The recycled concrete aggregate shown in Figure 1.1 can be defined as crushed concrete composed of aggregate fragments coated with cement paste or cement mortar from the demolition of the old structures or pavements that has been processed to produce aggregates suitable for use in new concrete. The processing, as with many natural aggregates, generally involves crushing, grading and washing. This removes contaminant materials such as reinforcing steel, remnants of formwork, gypsum board, and other foreign materials. The resulting coarse aggregate is then suitable for use in concrete. The fine aggregate, however, generally contains a considerable amount of old cement paste and mortar. This tends to increase the drying shrinkage and creep properties of the new concrete, as well as leading to problems with unworkable mix and strength. Therefore, many transportation departments have found that using 100% coarse recycled aggregate but with only about 10% to 20% recycled fines works well. Regarding the results of most of the previous research that has been done so far, the application of Recycled Aggregate is mostly currently in low quality/strength concrete, for example, pavement base and slab rather than used in structural concrete. The most common application of Recycled Concrete Aggregate is the use in concrete sub-base in road construction, bank protection, noise barriers and embankments, many types of general bulk fills and fill materials for drainage structures. After the removal of contaminants through selective demolition, screening, and/or air separation and size reduction in a crusher to aggregate sizes, crushed concrete can be used as new concrete for pavements, shoulders, median barriers, sidewalks, curbs and gutters, and bridge foundations; structural grade concrete; soil-cement pavement bases; moulded concrete bricks and blocks; bituminous concrete etc. However, there is an example of recycled concrete being used for part of the structural slabs in a high-rise building in Japan but there was no too much detail available on this project. According to research that has been conducted in Australia, current use of recycled aggregates is still only around 7% of road construction material in South Australia. Victoria Road also use recycled aggregate for their road base construction projects in Victoria but MainRoads in Queensland does not currently. Traditionally, the application of recycled aggregate is used as landfill. Nowadays, the applications of recycled aggregate in construction areas are wide. The applications are different from country to country. Concrete Kerb and Gutter Mix Recycled aggregate have been used as concrete kerb and gutter mix in Australia. According to Building Innovation Construction Technology (1999), Stone says that the 10mm recycled aggregate and blended recycled sand are used for concrete kerb and gutter mix in the Lent hall Street project in Sydney. Granular Base Course Materials According to Market Development Study for Recycled Aggregate Products (2001), recycled aggregate are used as granular base course in the road construction. It also stated that recycled aggregate had proved that better than natural aggregate when used as granular base course in roads construction. They also found that when the road is built on the wet sub grade areas, recycled aggregate will stabilize the base and provide an improved working surface for pavement structure construction. Embankment Fill Materials Market Development Study for Recycled Aggregate Products (2001) stated that recycled aggregate can be used in embankment fill. The reason for being able to use in embankment fill is same as it is used in granular base course construction. The embankment site is on the wet sub grade areas. Recycled aggregate can stabilize the base and provide an improved working surface for the remaining works. Paving Blocks Recycled aggregate have been used as paving blocks in Hong Kong. According to Hong Kong Housing Department (n.d.), recycled aggregate are used as typical paving blocks. A trial project had been started to test the long – term performance of paving blocks made with recycled aggregate in 2002. Backfill Materials Recycled aggregate can be used as backfill materials. Mehus and Lillestol (n.d) found that Norwegian Building Research Institute (n.d) mentioned that recycled concrete aggregate can be used as backfill materials in the pipe zone along trenches after having testing in laboratory. Building Blocks Recycled aggregate used as building blocks. Mehus and Lillestol (n.d) stated that Optiroc AS had used recycled aggregate to produce the masonry sound insulation blocks. The masonry sound insulation blocks that produced had met all the requirements during the laboratory testing. International Status Mehus and Lillestol (n.d.) stated that RESIBA had constructed a new high school in Sorumsand, outside the city of Oslo, Norway in 2001. Recycled concrete aggregate had been used in this project. Thirty – five percent of coarse aggregate were replaced by recycled concrete aggregate in the foundations, half of the basement walls and columns. Several tests were conducted based on fresh and hardened concrete properties and the results shown that the concrete with thirty – five percent of recycled concrete aggregate have good freeze – thaw resistance. The use of recycled concrete aggregate did not shown any noticeable increase in cracking. According to Grubl, Nealen and Schmidt (n.d.), there is a building project, the â€Å"Waldspirale† by Friedensreich Hundertwasser, made from concrete with recycled aggregate in Darmstadf from November 1998 to September 1999. Numerous tests were evaluated for freshly missed and also hardened concrete properties. The result shown that the consistency controlled method for concrete with recycled aggregate is applicable. And it leads to concrete of equal quality when compared with concrete made from natural aggregate. According to Regain (1993/94), recycled aggregate were used as capping and sub-base layers in housing development at North Bracknell, UK in 1993/94. Visual inspections and condition surveys were carried out by using the falling weight deflectometer in 1998. The result shown that the sections with recycled aggregate did not show any difference in appearance compared to the sections that using natural aggregate. The tests gave the larger values of elastic modulus in the recycled aggregate sections. According to Regain (2001), footway paving slabs are being replaced gradually in London Borough of Bexley. Recycled aggregate are used as coarse aggregate in the concrete mix with a 12:1 aggregate to cement mix Advantages There are many advantages through using the recycled aggregate. The advantages that occur through usage of recycled aggregate are listed below. Environmental Gain The major advantage is based on the environmental gain. According to CSIRO (n.d.), construction and demolition waste makes up to around 40% of the total waste each year (estimate around 14 million tones) going to land fill. Through recycled these material, it can keep diminishing the resources of urban aggregated. Therefore, natural aggregate can be used in higher –grade applications. Save Energy The recycling process can be done on site. According to Kajima Technical Research Institute (2002), Kajima is developing a method of recycling crushed concrete that used in the construction, known as the Within-Site Recycling System. Everything can be done on the construction site through this system, from the process of recycled aggregate, manufacture and use them. This can save energy to transport the recycled materials to the recycling plants. Cost Secondly is based on the cost. The cost of recycled aggregate is cheaper than virgin aggregate. According to PATH Technology Inventory (n.d.), the costs of recycled concrete aggregate are sold around $3.50 to $7.00 per cubic yard. It depends on the aggregate size limitation and local availability. This is just around one and half of the cost for natural aggregate that used in the construction works. The transportation cost for the recycled aggregate is reduced due to the weight of recycled aggregate is lighter than virgin aggregate. Concrete Network (n.d) stated that recycling concrete from the demolition projects can saves the costs of transporting the concrete to the land fill (around $0.25 per ton/ mile), and the cost of disposal (around $100 per ton). Beside that, Aggregate Advisory Service (n.d.) also state that the recycling site may accept the segregates materials at lower cost than landfill without tax levy and recycled aggregate can be used at lower prices than primary aggregate in the construction works. Job Opportunities There will be many people involved in this new technology, such as specialized and skilled persons, general workers, drivers and etc. According to Scottish Executive (2004), a Scottish Market Development Program is developed. The purpose of this program is to recycle the materials that arising in Scotland. This program will provide 150 new jobs in the Scottish industry. Sustainability The amount of waste materials used for landfill will be reducing through usage of recycled aggregate. This will reduce the amount of quarrying. Therefore this will extend the lives of natural resources and also extend the lives of sites that using for landfill. Market is Wide The markets for recycled concrete aggregate are wide. According to Environmental Council of Concrete Organization (n.d), recycled concrete aggregate can be used for sidewalk, curbs, bridge substructures and superstructures, concrete shoulders, residential driveways, general and structural fill. It also mentioned that recycled concrete aggregate can be used in sub bases and support layers such as unstabilized base and permeable bases. Disadvantages Although there are many advantages by using recycled aggregate. But there are still some disadvantages in recycled aggregate. Hard to have permit Jacobsen (1999) stated that it is hard to get the permit for the machinery that needed air permit or permit to operate during the recycling process. These has to depend on the local or state regulations whether this technology is implemented or not. Lack of Specification and Guidelines According to Kawano (n.d), there is no specification or any guideline when using recycled concrete aggregate in the constructions. In many cases, the strength characteristic will not meet the requirement when using recycled concrete aggregate. Therefore, more testing should be considered when using recycled concrete aggregate. Water Pollution The recycled process will cause water pollution. Morris of National Ready Mix Concrete Association (n.d) had mentioned that the wash out water with the high pH is a serious environmental issue. According to Building Green (1993), the alkalinity level of wash water from the recycling plants is pH12. This water is toxic to the fish and other aquatic life. Project Aim The aim for this on – going project is to determine the strength characteristic of recycled aggregate for application in high strength structural concrete, which will give a better understanding on the properties of concrete with recycled aggregate, where can be an alternative material to coarse aggregate in structural concrete.

Literature review of Recycled Aggregate Literature review of Recycled Aggregate Conventional concrete aggregate consists of sand (fine aggregate) and various sizes and shapes of gravel or stones. However, there is a growing interest in substituting alternative aggregate materials, largely as a potential use for recycled materials. While there is significant research on many different materials for aggregate substitutes (such as granulated coal ash, blast furnace slag or various solid wastes including fiberglass waste materials, granulated plastics, paper and wood products / wastes, sintered sludge pellets and others), the only two that have been significantly applied are glass cullet and crushed recycled concrete itself. Even though aggregate typically accounts for 70% to 80% of the concrete volume, it is commonly thought of as inert filler having little effect on the finished concrete properties. However, research has shown that aggregate in fact plays a substantial role in determining workability, strength, dimensional stability, and durability of the concrete. Also, aggregates can have a significant effect on the cost of the concrete mixture. Certain aggregate parameters are known to be important for engineered-use concrete: hardness, strength, and durability. The aggregate must be clean, without absorbed chemicals, clay coatings, and other fine materials in concentrations that could alter the hydration and bond of the cement paste. It is important to note the difference between aggregate and cement, because some materials have found use both as a cementitious material and as aggregate (such as certain blast furnace slags). Materials that have been researched or applied only as cement substitutes are addressed in another Technology Inventory article Cement Substitutes. Aggregate composed of recycled concrete generally has a lower specific gravity and a higher absorption than conventional gravel aggregate. New concrete made with recycled concrete aggregate typically has good workability, durability and resistance to saturated freeze-thaw action. The compressive strength varies with the compressive strength of the original concrete and the water-cement ratio of the new concrete. It has been found that concrete made with recycled concrete aggregate has at least two-thirds the compressive strength and modulus of elasticity of natural aggregate concrete. Field-testing has shown that crushed and screened waste glass may be used as a sand substitute in concrete. Nearly all waste glass can be used in concrete applications, including glass that is unsuitable for uses such as glass bottle recycling. Some of the specific glass waste materials that have found use as fine aggregate are non-recyclable clear window glass and fluorescent bulbs with very small amounts of contaminants. Possible applications for such waste-glass concrete are bike paths, footpaths, gutters and similar non-structural work. Lack of widespread reliable data on aggregate substitutes can hinder its use. To design consistent, durable recycled aggregate concrete, more testing is required to account for variations in the aggregate properties. Also, recycled aggregate generally has a higher absorption and a lower specific gravity than conventional aggregate. Research has revealed that the 7-day and 28-day compressive strengths of recycled aggregate concrete are generally lower than values for conventional concrete. Moreover, recycled aggregates may be contaminated with residual quantities of sulfate from contact with sulfate rich soil and chloride ions from marine exposure. Glass aggregate in concrete can be problematic due to the alkali silica reaction between the cement paste and the glass aggregate, which over time can lead to weakened concrete and decreased long-term durability. Research has been done on types of glass and other additives to stop or decrease the alkali silica reaction and thereby maintain finished concrete strength. However, further research is still needed before glass cullet can be used in structural concrete applications. The applications of recycled aggregate in highway construction as a road base material are very board and have been in use for almost 100 years. There has been much research based on the use of recycled aggregate that has been carried out all around the world. The research on recycled aggregate that has been carried out indicated that the successful application of crushed aggregate in concrete can be achieved. This successful research has been achieved in many countries, in particular in Europe; United States; Japan and China. This chapter presents literature reviews on the effects of various factors on the recycled aggregate from research from those countries. The major objective of most of the experiments or research on recycled aggregate is to find out the results in the strength characteristic area and what is the best method to achieve high strength concrete with recycled aggregate. Strengths of Recycled Aggregate Concrete Made Using Field- Demolished Concrete as Aggregate Tavakoli M. (1996) studied the compressive; splitting tensile and flexural strengths of 100% recycled coarse aggregate concrete and 100% natural sand to compare them with normal concrete made of natural crushed stone. The water-cement ratio was 0.3 and 0.4 in the concrete mix design. The test result shows the compressive, tensile and flexural strengths of RCA are little higher than the natural aggregate at the same size of 25.4mm at 28-day specimen. This indicates that if the compressive strength of the original concrete that is being recycled is higher than that of the control concrete, then the recycled aggregate concrete can also be made to achieve higher compressive strength than the control concrete. The results also indicates increase L.A. abrasion loss and water absorption capacity of recycled aggregates, which partly reflect the increased amount of water, adhering to the original stone aggregate, generally lead to reduced compressive strength of recycled aggregate concrete. Dhir et al. (1998) studied the effect of the cleanliness and percentage of the replacement of RCA. They found out that the degree of cleanliness of aggregate has significantly affected on the results of the properties of both the plastic and hardened concrete. The workability and compressive strengths both were lower than the quarried aggregate from 17% to 78% depending on the percentage of replacement of RCA. The results also indicated recycled aggregate has very high air content. Limbachiya and Leelawat (2000) found that recycled concrete aggregate had 7 to 9% lower relative density and 2 times higher water absorption than natural aggregate. According to their test results, it shown that there was no effect with the replacement of 30% coarse recycled concrete aggregate used on the ceiling strength of concrete. It also mentioned that recycled concrete aggregate could be used in high strength concrete mixes with the recycled concrete aggregate content in the concrete. Sagoe, Brown and Taylor (2002) stated that the difference between the characteristic of fresh and hardened recycled aggregate concrete and natural aggregate concrete is relatively narrower than reported for laboratory crush recycled aggregate concrete mixes. There was no difference at the 5% significance level in concrete compressive and tensile strength of recycled concrete and control normal concrete made from natural aggregate. Limbachiya (2003) found that there is no effect by using up to 30% of coarse recycled concrete aggregate on the standard 100mm concrete cube compressive strength. But when the percentage of recycled concrete aggregate used increased, the compressive strength was reducing. Behavior of Construction and Demolition Debris in Base and Subbase Application Pappjr et al (1998) studied using recycled aggregates in Base and Subbase applications. They found that recycled concrete yielded higher resilient modulus than the dense graded aggregate currently used. Furthermore, the results have been shown that recycled concrete have less permanent deformation than dense graded aggregate. They concluded that recycled concrete could be a valuable alternative to natural materials for base and subbase applications. Influence of recycled aggregate quality on concrete properties Sanchez de Juan et al. (2000) studied what is the maximum percentage, from 20% to 100%, replacement of recycled aggregate in concrete. The results showed that the compressive strength of recycled concrete is lower than that of a control concrete with equal water/cement ratio and same cement content. Recycled concretes with a percentage of recycled coarse aggregate lower than 50% show decreases in the range 5-10%, while for concretes with 100% recycled aggregates, decreases ranged from 10-15%. Experimental results also indicated that properties of conventional concretes and recycled concretes with same compressive strength when less than 20% of recycled coarse aggregate are used. The exception being modulus of elasticity was decreased until 10% can be found in recycled concretes. When the percentage of recycled aggregate is lower than 50%, tensile strength and drying shrinkage of recycled concrete is similar to conventional concrete with same compressive strength. As a result of the testing, all properties of concrete with a 100% of recycled coarse aggregate are affected. Some studies on durability of recycled aggregate concrete Mandal et al. (2002) studied the durability of recycled aggregate concrete and found that recycled aggregate had less durability than natural aggregate. However, when 10 percent replacement of cement by fly ash was used with recycled aggregate, the durability observed was increased. It significantly improved the compressive strength up to 46.5MPa, reduced shrinkage and increased durability to a level comparable to natural aggregate. Therefore, the results of this study provide a strong support for the feasibility of using recycled aggregate instead of natural aggregate for the production of concrete. Use of recycled aggregates in molded concrete bricks and Blocks Poon et al. (2002) developed a technique to produce concrete bricks and paving blocks from recycled aggregates. The test result showed that replacing natural aggregate by 25% to 50% had little effect on the compressive strength, but higher levels of replacement reduced the compressive strength. The transverse strength increased as the percentage of recycled aggregate increased. The concrete paving blocks with a 28-day compressive strength of at least 49MPa can be produced without the incorporation of fly ash by using up to 100% recycled aggregate. According to the study, recycled aggregate has been used in structural engineering. For example, a viaduct and marine loch in the Netherlands in 1998 and an office building in England in 1999. The project in the Netherlands had shown that 20 percent of the coarse aggregate was replaced by recycled aggregate. The project also indicated even there are some disadvantage of recycled aggregate such as being too weak, more porous and that it has a very higher value of water absorption. However, the study showed that these weaknesses could be avoided by using mechanized moulded concrete bricks. The workability also could be improved by poring the mix into the mould. Therefore, the performance of the bricks and blocks was also satisfactory in the shrinkage and skid resistance tests. Concrete with Recycled materials as Coarse Aggregates: Shrinkage and Creep Behavior Tawrwe et al. (1999) compared limestone aggregate with concrete rubble. They found the concrete rubble had a very high water absorption compared to the limestone aggregate (0.74% against 6.83% of dry mass). Furthermore the porous aggregate absorbed water slowly in some tests. For example, it was difficult to determine accurately the amount of water that had to be added to obtain suitable workability. The critical shrinkage of the limestone aggregate concrete was higher than the concrete rubble, but after a year the shrinkage was greater for the concrete rubble based aggregate. Treatments for the improvement of recycled aggregate Katz (2004) stated two methods to improve the quality of the recycled aggregates. The superplasticizer (1% weight of silica fume) was added to the solution of 10L of water and 1 kg raw silica fume to ensure proper ispersion of silica fume particles. After the silica fume impregnation, the SF treatment seems to improve significantly the compressive strength up to 51MPa at ranged from 23% to 33% at 7 days of the recycled aggregate concrete. Ultrasonic cleaning of the recycled aggregate to remove the loose particles and improve the bond between the new cement paste and the recycled aggregate, which, in turn, increased 7% of strength. Kantawong and Laksana (1998) mentioned that the fineness modulus and percentage of water absorption used instead with the recycled aggregate is higher than natural aggregate. The results of compressive strength of added reduce water admixture concrete is higher than the one that not added reduce water admixture concrete, ane the compressive strength of concrete produced that using recycled aggregate is higher than concrete using natural coarse aggregate. Sawamoto and Takehino (2000) found that the strength of the recycled aggregate concrete can be increased by using Pozzolanic material that can absorb the water. Mandal (2002) stated that adjusted the water/cement ratio when using recycled concrete aggregate during the concrete mixing can improved the strength of the recycled aggregate concrete specimens. From the obtained result, recycled aggregate concrete specimens had the same engineering and durability performance when compared to the concrete specimens made by natural aggregate within 28days design strength. Chen and Kuan (2003) found that the strength of the concrete specimens was affected by the unwashed recycled aggregate in the concrete. The effect will more strange at the low water cement ratio. These effects can be improved by using the washed recycled aggregate. Construction and Demolition Waste Recycling Reuse as Aggregate in Concrete Production Limbachiya (2004) studied the properties of recycled aggregate compared with natural aggregates and found out the density of RCA is typically 4-8% lower and water absorption 2-6 times higher. The results showed that a reduction in slump value with increasing RCA concrete mix. The results also slowed that up to 30% coarse RCA has no effect on the standard concrete cube strength but thereafter a gradual reduction with increasing RCA content occurs. This means that some adjustment is necessary of the water/cement ratio to achieve the equivalent strength with high proportions of RCA. Review on Recycled Process This section discusses the recycling process and method.

Several tests were conducted based on fresh and hardened concrete properties and the results shown that the concrete with thirty – five percent of recycled concrete aggregate have good freeze – thaw resistance. The use of recycled concrete aggregate did not shown any noticeable increase in cracking. According to Grubl, Nealen and Schmidt (n.d.), there is a building project, the â€Å"Waldspirale† by Friedensreich Hundertwasser, made from concrete with recycled aggregate in Darmstadf from November 1998 to September 1999. Numerous tests were evaluated for freshly missed and also hardened concrete properties. The result shown that the consistency controlled method for concrete with recycled aggregate is applicable. And it leads to concrete of equal quality when compared with concrete made from natural aggregate. According to Regain (1993/94), recycled aggregate were used as capping and sub-base layers in housing development at North Bracknell, UK in 1993/94. Visual inspections and condition surveys were carried out by using the falling weight deflectometer in 1998. The result shown that the sections with recycled aggregate did not show any difference in appearance compared to the sections that using natural aggregate. The tests gave the larger values of elastic modulus in the recycled aggregate sections. According to Regain (2001), footway paving slabs are being replaced gradually in London Borough of Bexley. Recycled aggregate are used as coarse aggregate in the concrete mix with a 12:1 aggregate to cement mix Advantages There are many advantages through using the recycled aggregate. The advantages that occur through usage of recycled aggregate are listed below. Environmental Gain The major advantage is based on the environmental gain. According to CSIRO (n.d.), construction and demolition waste makes up to around 40% of the total waste each year (estimate around 14 million tones) going to land fill. Through recycled these material, it can keep diminishing the resources of urban aggregated. Therefore, natural aggregate can be used in higher –grade applications. Save Energy The recycling process can be done on site. According to Kajima Technical Research Institute (2002), Kajima is developing a method of recycling crushed concrete that used in the construction, known as the Within-Site Recycling System. Everything can be done on the construction site through this system, from the process of recycled aggregate, manufacture and use them. This can save energy to transport the recycled materials to the recycling plants. Cost Secondly is based on the cost. The cost of recycled aggregate is cheaper than virgin aggregate. According to PATH Technology Inventory (n.d.), the costs of recycled concrete aggregate are sold around $3.50 to $7.00 per cubic yard. It depends on the aggregate size limitation and local availability. This is just around one and half of the cost for natural aggregate that used in the construction works. The transportation cost for the recycled aggregate is reduced due to the weight of recycled aggregate is lighter than virgin aggregate. Concrete Network (n.d) stated that recycling concrete from the demolition projects can saves the costs of transporting the concrete to the land fill (around $0.25 per ton/ mile), and the cost of disposal (around $100 per ton). Beside that, Aggregate Advisory Service (n.d.) also state that the recycling site may accept the segregates materials at lower cost than landfill without tax levy and recycled aggregate can be used at lower prices than primary aggregate in the construction works. Job Opportunities There will be many people involved in this new technology, such as specialized and skilled persons, general workers, drivers and etc. According to Scottish Executive (2004), a Scottish Market Development Program is developed. The purpose of this program is to recycle the materials that arising in Scotland. This program will provide 150 new jobs in the Scottish industry. Sustainability The amount of waste materials used for landfill will be reducing through usage of recycled aggregate. This will reduce the amount of quarrying. Therefore this will extend the lives of natural resources and also extend the lives of sites that using for landfill. Market is Wide The markets for recycled concrete aggregate are wide. According to Environmental Council of Concrete Organization (n.d), recycled concrete aggregate can be used for sidewalk, curbs, bridge substructures and superstructures, concrete shoulders, residential driveways, general and structural fill. It also mentioned that recycled concrete aggregate can be used in sub bases and support layers such as unstabilized base and permeable bases. Disadvantages Although there are many advantages by using recycled aggregate. But there are still some disadvantages in recycled aggregate. Hard to have permit Jacobsen (1999) stated that it is hard to get the permit for the machinery that needed air permit or permit to operate during the recycling process. These has to depend on the local or state regulations whether this technology is implemented or not. Lack of Specification and Guidelines According to Kawano (n.d), there is no specification or any guideline when using recycled concrete aggregate in the constructions. In many cases, the strength characteristic will not meet the requirement when using recycled concrete aggregate. Therefore, more testing should be considered when using recycled concrete aggregate. Water Pollution The recycled process will cause water pollution. Morris of National Ready Mix Concrete Association (n.d) had mentioned that the wash out water with the high pH is a serious environmental issue. According to Building Green (1993), the alkalinity level of wash water from the recycling plants is pH12. This water is toxic to the fish and other aquatic life. Project Aim The aim for this on – going project is to determine the strength characteristic of recycled aggregate for application in high strength structural concrete, which will give a better understanding on the properties of concrete with recycled aggregate, where can be an alternative material to coarse aggregate in structural concrete.

Literature review of Recycled Aggregate Literature review of Recycled Aggregate Conventional concrete aggregate consists of sand (fine aggregate) and various sizes and shapes of gravel or stones. However, there is a growing interest in substituting alternative aggregate materials, largely as a potential use for recycled materials. While there is significant research on many different materials for aggregate substitutes (such as granulated coal ash, blast furnace slag or various solid wastes including fiberglass waste materials, granulated plastics, paper and wood products / wastes, sintered sludge pellets and others), the only two that have been significantly applied are glass cullet and crushed recycled concrete itself. Even though aggregate typically accounts for 70% to 80% of the concrete volume, it is commonly thought of as inert filler having little effect on the finished concrete properties. However, research has shown that aggregate in fact plays a substantial role in determining workability, strength, dimensional stability, and durability of the concrete. Also, aggregates can have a significant effect on the cost of the concrete mixture. Certain aggregate parameters are known to be important for engineered-use concrete: hardness, strength, and durability. The aggregate must be clean, without absorbed chemicals, clay coatings, and other fine materials in concentrations that could alter the hydration and bond of the cement paste. It is important to note the difference between aggregate and cement, because some materials have found use both as a cementitious material and as aggregate (such as certain blast furnace slags). Materials that have been researched or applied only as cement substitutes are addressed in another Technology Inventory article Cement Substitutes. Aggregate composed of recycled concrete generally has a lower specific gravity and a higher absorption than conventional gravel aggregate. New concrete made with recycled concrete aggregate typically has good workability, durability and resistance to saturated freeze-thaw action. The compressive strength varies with the compressive strength of the original concrete and the water-cement ratio of the new concrete. It has been found that concrete made with recycled concrete aggregate has at least two-thirds the compressive strength and modulus of elasticity of natural aggregate concrete. Field-testing has shown that crushed and screened waste glass may be used as a sand substitute in concrete. Nearly all waste glass can be used in concrete applications, including glass that is unsuitable for uses such as glass bottle recycling. Some of the specific glass waste materials that have found use as fine aggregate are non-recyclable clear window glass and fluorescent bulbs with very small amounts of contaminants. Possible applications for such waste-glass concrete are bike paths, footpaths, gutters and similar non-structural work. Lack of widespread reliable data on aggregate substitutes can hinder its use. To design consistent, durable recycled aggregate concrete, more testing is required to account for variations in the aggregate properties. Also, recycled aggregate generally has a higher absorption and a lower specific gravity than conventional aggregate. Research has revealed that the 7-day and 28-day compressive strengths of recycled aggregate concrete are generally lower than values for conventional concrete. Moreover, recycled aggregates may be contaminated with residual quantities of sulfate from contact with sulfate rich soil and chloride ions from marine exposure. Glass aggregate in concrete can be problematic due to the alkali silica reaction between the cement paste and the glass aggregate, which over time can lead to weakened concrete and decreased long-term durability. Research has been done on types of glass and other additives to stop or decrease the alkali silica reaction and thereby maintain finished concrete strength. However, further research is still needed before glass cullet can be used in structural concrete applications. The applications of recycled aggregate in highway construction as a road base material are very board and have been in use for almost 100 years. There has been much research based on the use of recycled aggregate that has been carried out all around the world. The research on recycled aggregate that has been carried out indicated that the successful application of crushed aggregate in concrete can be achieved. This successful research has been achieved in many countries, in particular in Europe; United States; Japan and China. This chapter presents literature reviews on the effects of various factors on the recycled aggregate from research from those countries. The major objective of most of the experiments or research on recycled aggregate is to find out the results in the strength characteristic area and what is the best method to achieve high strength concrete with recycled aggregate. Strengths of Recycled Aggregate Concrete Made Using Field- Demolished Concrete as Aggregate Tavakoli M. (1996) studied the compressive; splitting tensile and flexural strengths of 100% recycled coarse aggregate concrete and 100% natural sand to compare them with normal concrete made of natural crushed stone. The water-cement ratio was 0.3 and 0.4 in the concrete mix design. The test result shows the compressive, tensile and flexural strengths of RCA are little higher than the natural aggregate at the same size of 25.4mm at 28-day specimen. This indicates that if the compressive strength of the original concrete that is being recycled is higher than that of the control concrete, then the recycled aggregate concrete can also be made to achieve higher compressive strength than the control concrete. The results also indicates increase L.A. abrasion loss and water absorption capacity of recycled aggregates, which partly reflect the increased amount of water, adhering to the original stone aggregate, generally lead to reduced compressive strength of recycled aggregate concrete. Dhir et al. (1998) studied the effect of the cleanliness and percentage of the replacement of RCA. They found out that the degree of cleanliness of aggregate has significantly affected on the results of the properties of both the plastic and hardened concrete. The workability and compressive strengths both were lower than the quarried aggregate from 17% to 78% depending on the percentage of replacement of RCA. The results also indicated recycled aggregate has very high air content. Limbachiya and Leelawat (2000) found that recycled concrete aggregate had 7 to 9% lower relative density and 2 times higher water absorption than natural aggregate. According to their test results, it shown that there was no effect with the replacement of 30% coarse recycled concrete aggregate used on the ceiling strength of concrete. It also mentioned that recycled concrete aggregate could be used in high strength concrete mixes with the recycled concrete aggregate content in the concrete. Sagoe, Brown and Taylor (2002) stated that the difference between the characteristic of fresh and hardened recycled aggregate concrete and natural aggregate concrete is relatively narrower than reported for laboratory crush recycled aggregate concrete mixes. There was no difference at the 5% significance level in concrete compressive and tensile strength of recycled concrete and control normal concrete made from natural aggregate. Limbachiya (2003) found that there is no effect by using up to 30% of coarse recycled concrete aggregate on the standard 100mm concrete cube compressive strength. But when the percentage of recycled concrete aggregate used increased, the compressive strength was reducing. Behavior of Construction and Demolition Debris in Base and Subbase Application Pappjr et al (1998) studied using recycled aggregates in Base and Subbase applications. They found that recycled concrete yielded higher resilient modulus than the dense graded aggregate currently used. Furthermore, the results have been shown that recycled concrete have less permanent deformation than dense graded aggregate. They concluded that recycled concrete could be a valuable alternative to natural materials for base and subbase applications. Influence of recycled aggregate quality on concrete properties Sanchez de Juan et al. (2000) studied what is the maximum percentage, from 20% to 100%, replacement of recycled aggregate in concrete. The results showed that the compressive strength of recycled concrete is lower than that of a control concrete with equal water/cement ratio and same cement content. Recycled concretes with a percentage of recycled coarse aggregate lower than 50% show decreases in the range 5-10%, while for concretes with 100% recycled aggregates, decreases ranged from 10-15%. Experimental results also indicated that properties of conventional concretes and recycled concretes with same compressive strength when less than 20% of recycled coarse aggregate are used. The exception being modulus of elasticity was decreased until 10% can be found in recycled concretes. When the percentage of recycled aggregate is lower than 50%, tensile strength and drying shrinkage of recycled concrete is similar to conventional concrete with same compressive strength. As a result of the testing, all properties of concrete with a 100% of recycled coarse aggregate are affected. Some studies on durability of recycled aggregate concrete Mandal et al. (2002) studied the durability of recycled aggregate concrete and found that recycled aggregate had less durability than natural aggregate. However, when 10 percent replacement of cement by fly ash was used with recycled aggregate, the durability observed was increased. It significantly improved the compressive strength up to 46.5MPa, reduced shrinkage and increased durability to a level comparable to natural aggregate. Therefore, the results of this study provide a strong support for the feasibility of using recycled aggregate instead of natural aggregate for the production of concrete. Use of recycled aggregates in molded concrete bricks and Blocks Poon et al. (2002) developed a technique to produce concrete bricks and paving blocks from recycled aggregates. The test result showed that replacing natural aggregate by 25% to 50% had little effect on the compressive strength, but higher levels of replacement reduced the compressive strength. The transverse strength increased as the percentage of recycled aggregate increased. The concrete paving blocks with a 28-day compressive strength of at least 49MPa can be produced without the incorporation of fly ash by using up to 100% recycled aggregate. According to the study, recycled aggregate has been used in structural engineering. For example, a viaduct and marine loch in the Netherlands in 1998 and an office building in England in 1999. The project in the Netherlands had shown that 20 percent of the coarse aggregate was replaced by recycled aggregate. The project also indicated even there are some disadvantage of recycled aggregate such as being too weak, more porous and that it has a very higher value of water absorption. However, the study showed that these weaknesses could be avoided by using mechanized moulded concrete bricks. The workability also could be improved by poring the mix into the mould. Therefore, the performance of the bricks and blocks was also satisfactory in the shrinkage and skid resistance tests. Concrete with Recycled materials as Coarse Aggregates: Shrinkage and Creep Behavior Tawrwe et al. (1999) compared limestone aggregate with concrete rubble. They found the concrete rubble had a very high water absorption compared to the limestone aggregate (0.74% against 6.83% of dry mass). Furthermore the porous aggregate absorbed water slowly in some tests. For example, it was difficult to determine accurately the amount of water that had to be added to obtain suitable workability. The critical shrinkage of the limestone aggregate concrete was higher than the concrete rubble, but after a year the shrinkage was greater for the concrete rubble based aggregate. Treatments for the improvement of recycled aggregate Katz (2004) stated two methods to improve the quality of the recycled aggregates. The superplasticizer (1% weight of silica fume) was added to the solution of 10L of water and 1 kg raw silica fume to ensure proper ispersion of silica fume particles. After the silica fume impregnation, the SF treatment seems to improve significantly the compressive strength up to 51MPa at ranged from 23% to 33% at 7 days of the recycled aggregate concrete. Ultrasonic cleaning of the recycled aggregate to remove the loose particles and improve the bond between the new cement paste and the recycled aggregate, which, in turn, increased 7% of strength. Kantawong and Laksana (1998) mentioned that the fineness modulus and percentage of water absorption used instead with the recycled aggregate is higher than natural aggregate. The results of compressive strength of added reduce water admixture concrete is higher than the one that not added reduce water admixture concrete, ane the compressive strength of concrete produced that using recycled aggregate is higher than concrete using natural coarse aggregate. Sawamoto and Takehino (2000) found that the strength of the recycled aggregate concrete can be increased by using Pozzolanic material that can absorb the water. Mandal (2002) stated that adjusted the water/cement ratio when using recycled concrete aggregate during the concrete mixing can improved the strength of the recycled aggregate concrete specimens. From the obtained result, recycled aggregate concrete specimens had the same engineering and durability performance when compared to the concrete specimens made by natural aggregate within 28days design strength. Chen and Kuan (2003) found that the strength of the concrete specimens was affected by the unwashed recycled aggregate in the concrete. The effect will more strange at the low water cement ratio. These effects can be improved by using the washed recycled aggregate. Construction and Demolition Waste Recycling Reuse as Aggregate in Concrete Production Limbachiya (2004) studied the properties of recycled aggregate compared with natural aggregates and found out the density of RCA is typically 4-8% lower and water absorption 2-6 times higher. The results showed that a reduction in slump value with increasing RCA concrete mix. The results also slowed that up to 30% coarse RCA has no effect on the standard concrete cube strength but thereafter a gradual reduction with increasing RCA content occurs. This means that some adjustment is necessary of the water/cement ratio to achieve the equivalent strength with high proportions of RCA.
