| 摘 要： | 通过试验研究橡胶混凝土的脆性.对橡胶混凝土圆柱体进行循环加载,得到它们的滞回曲线,从而求得橡胶混凝土的脆性指数.试验数据表明,与普通混凝土相比,分别用橡胶粉或者橡胶块代替粗骨料的橡胶混凝土的脆性指数有不同幅度的降低,材料的延性有所改善.

| Abstract: | The Brittleness of Rubberized Concrete was studied by experiment in the paper.Upon loading,unloading,and reloading on prepared cylindrical specimens,the hysteresis loops were drawn and brittleness index values were obtained.Experimental results show that brittleness index values of rubberized concrete whose coarse aggregate replaced by rubber powder or rubber block were lower than that of normal concrete,which meant that rubberized concrete had better ductility performance. |

| Keywords: | rubberized concrete brittleness index ductility performance |
