Abstract: Depending on the recycled aggregate replacement rate, complete stress-strain curve and elastic modulus specimen is prism concrete of 150 mm×150 mm×300 mm, of which 15 studies on the elastic modulus of recycled concrete Another of 15 to study complete stress-strain curve. We can see the elastic modulus descended gradually with replacement ratios increasing. The replacement ratios of RA have great influent on stress-strain curves of RCA. All stress-strain curves of RCA with different replacement ratios have almost same shapes, and like ordinary concrete have proportional limit, critical stress, peak value, inflection point and convergence point. The angles of the upward stage become small, both damage process and brittleness are increased with replacement ratios of RA increasing.
