Taking ordinary concrete C30 as the benchmark, technological indexed like water absorption, water-binder ratio, slump,strength,apparent densi-ty and cracking index of natural aggregate concrete and recycled aggregate concrete are respectively measured with experiment. The impact of different replacement rates of recycled aggregate on its mixture and physical and mechanical properties in settling and hardening process are also studied with com-parative analysis method.
