PRACTICAL APPLICATION OF ENVIRONMENTALLY-FRIENDLY RECYCLED AGGREGATE CONCRETE

Abstract

We developed the original production method of recycled aggregate concrete: the manufacturing process of recycled aggregate is simple; no removal of original mortar is conducted, and natural aggregate is replaced with recycled aggregate according to the required quality of concrete. This paper describes the various quality of that recycled aggregate concrete: strength characters, durability, fire resistance, structural behavior, performance for construction work, the original production method of recycled aggregate concrete when ready mixed concrete plant is not available, and the evaluation of cost effectiveness and environmental impact.
