Abstract
The regeneration aggregate, natural aggregate, P·O42.5 R Portland cement, coal fly ash, and slag powders S95 graining blast furnace, homemade P(AA-co-MA)/PEG carboxylic acid water reducing agent, were used together with recycled concrete aggregate in different regeneration rates to prepare recycled concrete (RC). The influences of different renewable aggregate ratios on the basic RC replacement mechanical properties, uniaxial compression stress and strain curve, and the elastic modulus and rebound value were investigated.The results show that RC mechanical properties decreases with renewable aggregate replacement rate increasing. The prolongation can reduce the reduced span.
