研究了粗集料粒径、集料体积率和粗集料的种类对混凝土断裂能和断裂韧性的影响 ;并从细观结构上分析集料对混凝土断裂性能作用机理
The effects of coarse aggregate size, aggregate volume ratio and coarse aggregate type on the fracture energy and fracture toughness of concrete were studied. The mechanism of aggregates on the fracture behavior of concrete was analyzed from the meso-structure
