摘　　要：利用正交试验法,设计了9组添加不同玄武岩纤维掺量和长度的混合骨料混凝土,研究云砼石代石子率、玄武岩纤维掺量、玄武岩纤维长度对混凝土性能的影响。试验结果显示:对混凝土抗压强度和劈裂抗拉强度的影响程度由强到弱分别是玄武岩纤维掺量、云砼石代石子率和玄武岩纤维长度;最佳配合比云砼石代石子率为10%、玄武岩纤维掺量为0.2%、玄武岩纤维长度为6 mm。Using orthogonal test method,9 groups of mixed aggregate concrete with different basalt fiber content and length were designed to inspect the effects of stone replacement ratio,basalt fiber content and basalt fiber length of cloud concrete on concrete properties.The results of the tests indicate that the impact on the compressive and tensile strengths of concrete decreases in the order of basalt fiber content,ceramic aggregate replacement rate,and basalt fiber length.The optimal mix ratio of the cloud concrete stone replacement rate is 10%,the basalt fiber volume content is 0.2%,and the basalt fiber length is 6 mm.
