摘要
为优化玄武岩纤维对聚合物矿物混凝土(PMC)的组分配比,通过正交实验,制备玄武岩纤维增强PMC,分析了各因素对玄武岩纤维增强PMC抗压强度的影响。结果表明,各因素对玄武岩纤维增强PMC抗压强度的影响显著性由大到小依次为:黏合剂E44与E51质量比,玄武岩纤维加入量,骨料用量,玄武岩纤维长径比。推荐玄武岩纤维增强PMC的最佳组分为:黏合剂E44与E51质量比40∶60,玄武岩纤维加入量0.4%,骨料用量80%,玄武岩纤维长径比70,抗压强度为112.38 MPa。对最佳组分中的玄武岩纤维偶联处理后,PMC抗压强度又提高14.1%,达到128.23 MPa。
Polymer mineral concrete （PMC） reinforced by basalt fiber was fabricated by orthogonal tests to optimize the component mixture ratio. The law of how the factors affect the compression strength of PMC reinforced by basalt fiber was analyzed. The results showed that the significant influences on compressive strength of PMC reinforced by basalt fiber from large to small were the E44 and E51 mass ratio of adhesive, the amount of basalt fiber, the amount of aggregate and the aspect ratio of basalt fiber. The suitable constitute of PMC reinforced by basalt fiber were 40 ： 60 with the E44 and E51 mass ratio of adhesive, 0.4% basalt fiber, 80% aggregate and the aspect ratio of 70, the compressive strength was 112.38 MPa. After coupling treatment of the suitable constitute of PMC reinforced by basalt fiber, the compressive strength of PMC was 128.23 MPa, 14.1% higher than that of PMC without coupling treatment.
