A Study for Developing Construction Goods by Waste-Concrete

As Waste-concretes generated in construction field are increasing, it is becoming difficult and expensive to dispose them. For environmental reasons, many attempts have been made to find ways of reusing these materials. However, very little waste-concrete is currently recycled or reused anywhere on the world. Recycled concrete is mainly used as nonstabilized base of sub-base in highway construction. In this study, in order to promote the reuse of the waste-concretes, no-fines concrete blocks using recycled concrete aggregates were produced and their properties are evaluated. From the test results about strengths, pemeability, and durability, it is known that to use recycled aggregates for construction goods is promising and economical.
