摘要
界面特征对断裂性能的影响存在一定的随机性,研究分析了层布式混凝土的断裂性能、界面粘结强度对层布式钢纤维混凝土断裂韧度的影响以及钢纤维拉拔韧度对层布式钢纤维混凝土断裂性能的影响,研究发现,钢纤维-水泥石界面特征对层布式钢纤维混凝土的断裂性能影响显著。
The effects of interfacial characteristics on fracture properties have certain randomness. In this research, the fracture properties of layered concrete and the influence of interfacial bond strength on the fracture toughness of layered steel fiber reinforced concrete are analyzed. The effect of steel fiber drawing toughness on the fracture energy of layered steel fiber reinforced concrete is also analyzed. Finally, it is found that the interfacial characteristics of steel fiber and cement have a more obvious effect on the fracture properties of the layered steel fiber reinforced concrete.
