| 摘 要： | 研究了玄武岩纤维、聚乙烯醇纤维、聚丙烯纤维单掺及复掺对砂浆抗渗抗裂性能、吸水率、抗压抗折强度、线膨胀率的影响。结果表明,纤维能提高砂浆的抗渗抗开裂性能,降低砂浆吸水率,提高砂浆柔韧性,产生一定的膨胀以抵抗砂浆的内部收缩。纤维增强干混砂浆,复掺比单掺效果好。单掺时,增强效果为聚乙烯醇纤维>玄武岩纤维>聚丙烯纤维;复掺时,玄武岩纤维:聚乙烯醇纤维:聚丙烯纤维=1:0:2时,砂浆的抗渗抗裂性能及力学性能达到最佳。

| Abstract: | The influences of multi-mixing basalts fibers(BF),polyvinyl alcohol fiber(PVA) and polypropylene fiber(PPF) on impermeability,anti-cracking,water absorption,compressive strength,flexural strength,linear expansion rate of the mortar are investigated.The results show that fiber can improve the impermeability,anti-cracking and flexibility,reduce the water absorption of mortar,and resist internal shrinkage of mortar by producing certain expansion.Meanwhile,the properties of mortar is better reinforced with fibers multi-mixed than only mixed,and when fibers only-mixed,enhancing effect: PVA>BF>PPF.However,the impermeability,anti-cracking and mechanical properties of mortar reached optimum when BF: PVA: PPF=1:0:2. |
