摘要:
 掺加聚乙烯醇（PVA）纤维或者玄武岩（BF）虽可改善水泥砂浆的物理力学性能，但有一定局限性。为得到性能更优的复合材料，将两种纤维混掺入水泥砂浆中。在总体积掺量不变的条件下，设计了两种纤维以不同配比混掺的试验组S3~S9与不掺加纤维、单掺PVA纤维和单掺BF纤维的对照组S0、S1和S2对比试验方案。进行了单掺纤维以及两种纤维按不同比例混掺对水泥砂浆的流动性、强度、韧性以及干燥收缩性能试验。测试结果表明:将PVA纤维与BF纤维以恰当比例加入到水泥砂浆中，对其综合性能有很大提高；本试验条件下，纤维掺量比为V（PVA）∶V(BF)=2∶3时最佳。
Abstract:
 Although adding polyvinyl alcohol (PVA) fiber or basalt (BF) can improve the physical and mechanical properties of cement mortar, there are some limitations. In order to obtain the composite material with better performance, the two kinds of fibers are mixed into the cement mortar. Under the condition of constant volume fraction, the experimental groups S3~S9 mixed with two kinds of fibers at different ratios were designed for comparison with the control groupsS0, S1 andS2 mixed with no fiber, PVA fiber and BF fiber. The fluidity, strength, toughness and dry shrinkage properties of cement mortar mixed with single fiber and two kinds of fiber in different proportions were tested. The test results show that the comprehensive properties of cement mortar are greatly improved when PVA fiber and BF fiber are added into the cement mortar in proper proportion. Under the condition of this test, the optimal fiber content ratio is V(PVA) ∶V(BF)=2∶3.
