中文摘要：

为了研究短切玄武岩纤维增强混凝土（BFRC）基本力学性能及其受纤维掺量的影响。通过试验的方法,开展了这种新型复合建筑材料在不同纤维体积掺量情况下的抗劈拉力学性能研究。试验结果表明：混凝土掺入0.05%、0.1%、0.15%、0.2%、0.25%、0.3%六种不同体积含量的玄武岩纤维后,混凝土的坍落度出现不同程度的降低,试件的劈拉强度得到不同程度的提高,且提高幅度与连续玄武岩纤维（CBF）的体积掺量有直接关系。对比直掺法和预处理法两种制备工艺,在条件相同时下,预处理掺入方法所制备的BFRC的增强、增韧效果要优于直掺法制备的BFRC。结论：玄武岩纤维混凝土具有良好的力学性能,纤维的掺量和制备工艺的不同均会在不同程度上影响其抗劈拉性能。

英文摘要：

In order to study the basic mechanical properties of chopped basalt fiber reinforced concrete （BFRC） and the impact of basalt fiber reinforced concrete by fiber content. Experiments are conducted to examine the splitting tensile strength of this new composite con- struction material at different fiber volume fractions.The results show that the addition of fiber to concrete is at six different levels of volume fractions ,namely 0.05% ,0.1% ,0.15% ,0.2% ,0.25% ,0.3%, can decrease the slump of concrete and increase the splitting tensile strength in varying degree.Moreover,the degree of improvement is positively correlated with volume fraction of continuous basalt fiber （CBF） .When direct mixing method and pretreatment method are compared while holding other conditions constant, it is found that BFRC produced by pretreatment method demonstrates better strengthening and toughening effects than direct mixing method.Conclusion that with the research findings presented above,it concludes that BFRC has favorable mechanical properties, however, fiber volume frac- tion as well as production method will affect its performance on splitting tensile strength in different extent.
