recycled aggregate concrete%compressive strength%ultrasonic-rebound comline method
采用再生粗骨料替代率分别为0%,30%,70%,100%的再生混凝土试块,利用超声回弹综合法进行了系统的抗压强度检测试验研究,同时测出了不同荷载作用下的超声声速,通过试验得出再生混凝土超声声速和回弹值的变化规律。

The compressive strength of recycled concrete were tested used ultrasonic-rebound combined method, whose substition rates are 0% , 30% ,70% and 100% . Ultrasonic velocity was also measured under different loads. It obtained that the ultrasonic velocity and rebound value change rule of recycled concrete from test.
