aggregate index

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.

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。
