摘要
计算不同粗集料粒径、不同集料体积率和不同种类粗集料混凝土断裂能和断裂韧性 ;测试混凝土断裂时的声发射事件数 ;
The tests were carried out to study the effect of the size and type of and the volume rate of aggregates on fracture energy and toughness of high strength concrete (HSC) and the hits of acoustic emission in three point bending (AE) fracture toughness testing.The relationship between fracture properties of concrete and AE hits was analyzed.
