Abstract |
Concrete is an excellent material considered to be forever useful for structures and infrastructures. Because, the purchase of materials is easy, Besides, the price of concrete is inexpensive, and compressive strength is very high generally. A glaring defect of concrete, however, is that it is very difficult to recycle. The problems caused by concrete which is difficult to recycle are waste disposal, limestone exhaustion, and exhaustion of aggregate resources and so forth. In addition, a large quantity of waste concrete by dismantling of concrete makeup increases by re-construction and redevelopment in construction industry annually. However, much waste concrete are filled up in soil or it is thrown away illegally. The best way to solve these problems is to make the total amount of concrete reusable over and over again as structure material like steel and aluminum. The purpose of this study is to analyze problems by waste concrete in our country and suggest the new recycling method of waste concrete and investigate the recovery possibility of hydrated performance of hydrated cement paste for the development of recyclable concrete. |
