Recycled Concrete Aggregate and Implementation Problem

Recycled Concrete Aggregate and Implementation Problem Aggregate is one of the most vitally important materials in use for production as it profoundly influences concrete properties and performances. In terms of volume, aggregate is now one of the most widely used materials in the construction industry and, consequently, its treatment at the point of demolition is attracting mush interest. This is to represent total aggregate production, including usage in concrete and road base. Aggregate usage in concrete constitutes perhaps between 25 and 35 per cent of the total aggregate production. The sheer bulk of global aggregate usage is staggering. The above inevitably impacts on the environment due to the great huge quantity of general and construction waste materials or from building demolition site generated in developed countries. The disposal of all this waste has become a harsh social and environmental problem. This is a large burden on the worldà ¢Ã¢â€š ¬Ã¢â€ž ¢s natural resources and an increasingly expensive problem for solid waste management. Therefore, a possible alternative aggregate method to overcome this issue may be using recycled concrete aggregate instead of natural aggregate in construction task. The solution not only helps preserve and expand the natural resources, but also can reduce waste disposal costs as well as the removal of waste at landfills requirements. In this project, the order most important issue is to determine the best solution to make the recycled concrete aggregate economical for most infrastructure tasks especially in structural concrete. The degree of potential recycling of construction waste will show how the changes to become a new source or production, and find out whether it applies to, or less in Malaysia. Therefore, it can become a reference of implementation to the developers and contractors or increase recycling percentage of construction waste of their construction project. RESEARCH GOAL 1.2.1 TITLE The use of recycled concrete aggregate and implementation problem recycle in Malaysia. 1.2.2 AIM The research is to study how the recycled concrete aggregate be produced and its application. Besides that, the research also to examine the implementation problem for recycling concrete or aggregate in Malaysia construction industry. 1.2.3 OBJECTIVE 1) To define the method of recycling aggregate for use in concrete 2) To find out the application of recycled concrete aggregate 3) To determine the implementation problem of recycling concrete or aggregate in Malaysia. HYPOTHESIS Although the concrete or aggregate waste in Malaysia increasing, but Malaysia does not recycling concrete or aggregate rather than other country, such as Japan. RESEARCH QUESTION What are the factors affecting recycling concrete aggregate? How the implementation of recycling concrete aggregate in Malaysia compare with other country. BACKGROUND The recycled concrete aggregate 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. (Environmental Council of Concrete Organizations, 1999)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. (G. D. Taylor, 1991) 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, such as bituminous concrete. (Environmental Council of Concrete Organizations, 1999) SCOPE OF STUDY This research will identify about the recycle collection method, technical and process of aggregate is being study. Besides that, is to study the application of recycled concrete aggregate in construction industry. Lastly is the factor which may affecting the recycling potential such as, economic benefit, environment consideration and carry out the recycle service of concrete aggregate also a path of scope of study. The data and information were collected through literature reviews, questionnaires, and case study, all of these are facts and no assumptions have been made. RESEARCH METHODOLOGY In this research paper, information and data will be collected by 3 major approaches, the primary data source which will be postal questionnaire and interview. Secondary data source is literature review. These research methods are being chosen other than the case study because it is more suitable to be used in the research and can be done in a larger scope. Literature study Reference Books and Article In this research, I will get the information from library resource and reference books. Literature review on the topic of this research can find out from Library College. I have also refers the senior dissertation as a references or guideline in order to get some scheme to complete my research. Electronic information For the electronic information, I will search the information from websites for example www.google.com, www.yahoo.com, emerald are used to find the relevant information regarding to my objective and summary for article. Questionnaires For the questionnaire is prepared in order to achieve the objectives. I would like to use postal questionnaires method, which can collect broader perception and data for research analysis and facilitate the outcome of this study. The questionnaires is designed to answers the objective that has been outlined. The questionnaire is distributed to selected construction firm company and experience personnel such as main contractor. In order to obtain a high accuracy of survey, 30 sets of questionnaire are sending out. The next step after the data collection would be data analysis. This method includes compiling all the data collected. The survey is carried out to further look deep into the implementation problem and its factor of recycling in Malaysia construction industry. Interview I would like to use interview as my survey. I selected this methodology because it is face to face communication and can obtain direct respond. Interview methodology will be the structure interview. The interviewees for my survey will be the experience contractor or recycling company. Form the interview, interviewees can provide the right information, valuable opinion, and experience about the factor and implementation problem may affect the recycling potential in Malaysia 1.6 CONTENT OUTLINE Chapter 1: Introduction Chapter 2.1: Recycling and reuse concrete aggregate recycling method for aggregate, which use as concrete Standards and specifications of recycled concrete aggregate Chapter 2.2: The advantages or disadvantages of reuse the recycled material waste Cost, quality and properties Source and environment Chapter 2.3: The application of recycled concrete aggregate The use of recycled concrete material in construction industry Chapter 2.4: The implementation problem recycling concrete aggregate in Malaysia The status of implementation to recycling concrete aggregate The factor of implementation problem recycling concrete aggregate Chapter 5: Designing the case study and research methodology Chapter 6: Analysis and evaluating the case study evidence Chapter 7: Recommendation and conclusion

The Ninja :: essays research papers

Master of the Orient THE NINJA Born and raised in New York City, Eric Lustbader graduated from Columbia University in 1969. Lustbader has had a number of fascinating best-selling novels, including Black Heart and Angel Eyes, he introduced Elton John to the American music scene. He spent fifteen years in the music industry in various capacities, including working for both Elektra and CBS Records. He is a former writer for Cash Box magazine where he wrote lead stories on new rock acts. In that capacity, he was the first person in the United States to predict the success of Jimi Hendrix, David Bowie and Satana, among many others. Lustbader has taught in the All-Day Neighbourhood School Division of the NYC Public School System and has also taught pre-schoolers in special early Childhood programmes. Eric Lustbader, who travels worldwide in researching his novels, lives in Southampton, New York, with his wife Victoria Lustbader, who works for the Nature Conservancy. Well, I don't want to give the whole story away in this report, so I am going to summarise the story very briefly. The book isn't really just about a few selected people, but instead the author tries to see it from a lot of different perspectives. Therefore the reader get to know a variety of personalities. The Ninja is a high-voltage novel of intrigue and sensuality, richly characterised, fuelled by relentless suspense, an extraordinary thriller, least to say. If there's a main character in the book I think it would be Nicholas Linnear, a man of half-English, half-Oriental origin. A quite special man I will tell you more about later in this report. Anyway, the story begins with a murder, a clean, silent and mysterious murder. The police don't have a clue, so they call in Nicholas, an expert on this type of murders. Nicholas doesn't want to tell the others in the beginning, but he has his thoughts. As the story continues he start to split up the problem and suddenly everything is crystal clear. This isn't the usual type of murder, instead something even worse. An assassination, performed by a man bound by the blackest code of honour and skilled in the deadliest martial arts. This was the work of a ninja, a far remnant of the East. Nicholas must fight against a past he can't escape, trapped in a web of old lust and present passions, he uses all his skill and knowledge to survive.

Psychology Post Labor Day

This Sync drone results in anxiety, lack of motivation, difficulty concentrating and a feeling of e emptiness during the first few weeks of returning to work. There is a lot of factual inform action that is used to back up this idea. Most of the research is professionally studied and scientifically proved. However, some evidence is stronger than others. This article provides a lot of evidence. This article is mostly scientific because almost all of the information comes from professional doctors, journals, or SST dies.For example, a study of 96 Dutch workers â€Å"found that health and wellbeing return De to pre vacation levels during the first week back at work. † This was conducted by pro fissionable and published in the journal Work and Stress. The article also states information on and then tells the readers where that information came from, weather it was a jog renal or a person. For example, after the article explains to be alert for symptoms of Pos t Vacation Syndrome, it refers to its source, â€Å"†¦ Says Katherine Mueller, assistant director o f the Center for Integrative Psychotherapy in Allentown, P. † The article gives a thou rough description of who the person is. Her occupation/ position and her location. Some evidence is slightly stronger scientifically than others because of its accuracy. Not all the people who are mentioned in this article are 100% correct but they are not war Eng either. Some evidence gives a more accurate description than others. For example, † An estimated 6% of the U. S. Population suffers from SAD† (Seasonal Affective Dies order) This piece of evidence gives a numerical value which makes it more accurate than the statements above.Most evidence in this article is factual however there are some opinions. Facts are pieces Of information that are scientifically proven while opinions are the way someone thinks and their viewpoint on a topic. For example, Emily Clicking has an opinion on children' s' and adults' mindsets on going back to school. ‘†General Y, kids can't wait to go back to school. For parents, that means months of purchasing , planning, nagging, chauffeuring, chaperoning and negotiating. † This is an opinion because SE it is not true for all children and parents to view going back to school that way.That SST atonement reflects more on Clinician's point of view than on scientifically proven facts. If Clicking would have mentioned a percentage of how many kids are excited to go back to school and how many parents are not excited for the school year to begin, it would b e a more reliable source. Findings in this article are trustworthy because it uses a lot of sources such as different people and different studies in different journals. This create s an unbiased argument.

Kinship and Politics - 1504 Words

How do these texts illustrate the relationship between kinship and politics? In Greek Mythology, the power of right is passed by kinship in generations, and people’s belief in gods leads their life and their acts show gods’ will. In the meanwhile, politics originally indicates certain relationships are between politics and groups of individuals. Moreover, politics is always referred to methods, including the purpose and the use of power, for addressing impacts on the tendency of those individuals’ performance, as well as their engagement and activities in civic affairs. In result of that, theories of political behavior are aimed at explicating the influences that define an individual’s behaviors, opinions, and participation in civic†¦show more content†¦Athena brought in a new trial system, the introduction of jury, although she still respected that the male should be honored above all else for the sake of that she was born from Zeus’s thigh without any women’s distribution. Athena respects men above all else and so supports Orestes. We can have a look at texts below No mother gave me birth. I honor the male, in all things but marriage. Yes, with all my heart I am my Father’s child. I cannot set more stores by the woman’s death. She killed her husband, guardian of their house. Even if the vote is equal, Orestes wins. These texts provide Apollo and Athena the materials that they found evidences to support the thought of not guilty of Orestes. The violence in the old system has fallen to a continuing circle which forced the gods to find out a settlement of a new system of justice, in which the moral conflicts and disputes would fairly be resolved. The gods themselves could not judge cases, or else the world would be caught in the crossfire of the gods as it had during the Trojan War Thus, in the demand of the new system, the settlement at the end illustrates the relationship between kinship and politics, which is that the establishment of court and the introduction of jury has its own political influence.
