摘要：
Through a series of experiments, we studied the compressive strength and elastic modulus (E-c) of recycled concrete (RC) specifically. In my work, RC specimens contain C20, C30 & C40 these three kinds of compressive strength levels by different recycled coarse aggregate contents (30%, 50% & 100%). The results show that under the same strength level, the cubic compressive strength (f(cu)) and prismatic compressive strength (f(c)) are the highest by the substitution at 30%. The elastic modulus of RC is lower than natural concrete (NC), and with the recycled coarse aggregate contents increase, it reduces. While with the increase of water-cement ratio (W/C), recycled concrete compressive strength and elastic modulus improve significantly. In addition, put forward a new equation on the relationship between E-c and f(cu) of the RC.
