摘要：研究了在玄武岩纤维体积掺量分别为0.1%、0.2%、0.3%，长度分别为6、12、18 mm条件下，玄武岩纤维增强水泥基复合材料试件的抗压强度、劈裂抗拉强度及破坏模式。通过试验可知：抗压和劈裂抗拉试验中，破坏模式均为脆性破坏和具有延性特征的破坏2种模式，加入玄武岩纤维能明显提高试件的抗压、抗拉强度，且脆性效果得到明显改善。当纤维体积掺量为0.1%、长度为6 mm时，立方体抗压强度最高，为49.72 MPa；当纤维体积掺量为0.2%、长度为12 mm时，劈裂抗拉强度最高，为3.63 MPa。

Abstract：Compressive strength，splitting tensile strength and failure mode of basalt fiber reinforced cement composites specimen were studied when the fiber volume content and fiber length were 0.1%、0.2%、0.3% and 6，12，18 mm，respectively. It can be seen from the tests that the failure modes in the compression and split tensile tests are brittle failure and ductile failure. The addition of basalt fiber can obviously improve the compressive and tensile properties of the specimen，and the brittleness effect is obviously improved. When the fiber content is 0.1% and the length is 6 mm，the compressive strength of the cube reached the highest of 49.72 MPa. When the fiber content was 0.2% and the length was 12 mm，the splitting tensile strength reached the highest of 3.63 MPa.
