In this paper,the recycled coarse aggregate was prepared from waste concrete and brick,in which the waste concrete coarse aggregate was substitute for waste brick aggregate with 0%,10%,15% and 30%. The damage of recycled concrete was detected by ultrasonic wave,and it was measured by the decay of the ultrasonic wave velocity. The ultrasonic experiment was carried out on the recycled concrete specimen under uniaxial compression load condition. The effect of uniaxial compressive stress on the damage of recycled concrete under different replacement rates of waste bricks was obtained through experiments. The results present that the replacement rate of waste bricks has a great effect on the damage of recycled concrete under uniaxial compression. Finally,for the uniaxial compressive stress coefficient,which is the main factor affecting the damage of recycled concrete,the damage relation model of recycled coarse aggregate concrete containing brick is established.
