@@@@Compressive strengths of recycled aggregate concrete with different recycled aggregates replacement ratios at 7 d,28 d,60 d ages are investigated respectively. Failure process and failure mode of RAC are analyzed. The influences on compressive strength with same mix ratio and different RA replacement ratios are also analyzed. And the reason is investigated in this paper. The experimental results indicate that compressive strength of recycled concrete at 28 d age can reach the standard generally,it is feasible to mix concrete with recycled aggregates.
