摘要
采用混凝土断裂能试验研究了使用磨细矿渣和硅灰配制的高强度高性能混凝土的断裂脆性。结果表明,磨细矿渣和硅灰的复合使用显著提高了混凝土的抗压强度、劈裂抗拉强度和弹性模量,但同时降低了混凝土的断裂能和特征长度值,使混凝土的脆性进一步增大。
Fracture energy of concrete was measured for studying the fracture brittleness of the high performance concrete mixed ground granulated blastfurnace slag(GGBFS)and silica fume.The combination of GGBFS and silica fume significantly increased compressive strength,splitting tensile strength and elastic modulus of concrete,while decreased fracture energy and characteristic length,and further increased brittleness of concrete.
