APPLICATION AND PRODUCTION OF RECYCLED COARSE AGGREGATE

In this paper,the preparation technique of recycled aggregate is introduced,the production process of recycled aggregate is hereby proposed and the performance of recycled aggregate and recycled concrete are furthermore studied.By means of advanced process,high performance recycled aggregate satisfies the requirements from the codeRecycled coarse aggregate for concrete(GB/T 25177-2001) and Recycled fine aggregate for concrete and mortar(GB/T 25176-2001).Additionally,the corresponding recycled concrete has been applied in the construction and suffices for the structural engineering.
