摘要
提出集料在高强混凝土断裂过程的两种机理 ,并采用能量观点分析这两种机理 ;计算了不同集料体积率和不同集料混凝土断裂能 ,测试混凝土断裂时的声发射事件数 ;
The paper advances two mechanisms about effect of aggregate during fracture of high strength concrete and adopts the point of energy to analysis of the mechanisms. It calculates two kinds of fracture energy and tests the hits of acoustic emission during fracturing. Furthermore, the paper applies the fracture energy and hits of concrete fracturing crackle to validity check of the effect mechanisms .
