摘　　要：研究玄武岩纤维珊瑚混凝土基本力学性能以及不同纤维掺量下对珊瑚混凝土的影响及变化趋势。试验结果表明:合理的玄武岩纤维掺量对混凝土的抗压、劈拉、抗折强度提高均有增强效果,但最优掺量不尽相同。纤维掺量为4 kg/m^3时,抗压、劈拉强度增幅最大,分别为10.88%和3.77%;纤维掺量为2 kg/m^3时抗折强度提升效果最明显,增幅为24.07%。In order to study the basic mechanical properties of basalt fiber coral concrete and the influence of different fiber content on coral concrete and its changing trend.The results showed that the appropriate basalt fiber content has an enhanced effect on the concrete′s compressive strength,splitting tensile strength and flexural strength,but the best fiber content is not the same.When the fiber content is 4 kg/m3,the compressive and splitting tensile strengths increase the most,which are 10.88%and 3.77%.When the fiber content is 2 kg/m3,the flexural strength improvement effect is the most obvious,with an increase of 24.07%.
