摘　　要：水泥基材料的抗渗性能与其耐久性直接相关.采用测试不透水性提高率的方法,研究了纤维类型及纤维参数对水泥砂浆抗渗性能的影响.结果表明:掺加纤维能够显著提高砂浆的抗渗性能,纤维类型及纤维掺量、长度、直径、截面形状、表面处理方法等对砂浆的抗渗性能都有所影响.The anti-permeability property of cementious materials has direct relation with their durability, and becomes the research focus again for their durability problem being more and more serious. So the effect of fiber kinds and factors on anti-permeability of cement mortar was studied using the method of testing increased ratios of water-proof. Experimental results show that fiber mixed into cement mortar can obviously improve its anti-permeability, and fiber kinds, volume fraction, length, diameter, cross-section shape and methods of surface modification all have certain effects on the anti-per-meability of cement mortars.
