摘　　要：混凝土抗渗性能是衡量混凝土耐久性的重要指标。通过纤维素纤维混凝土的抗渗性能试验,研究了纤维掺量对C 50高强度混凝土抗渗性能的影响规律,分析了影响纤维素纤维混凝土渗透性能的主要因素。试验结果表明:纤维素纤维显著提高了混凝土的抗渗性能,随着纤维掺量的增加,混凝土渗透系数不断减小,抗渗性能逐渐提高,即使纤维素纤维掺量为0.9 kg/m3,也能使混凝土抗渗性能得到明显改善。The anti-permeability of concrete is one of important indexes of the durability of concrete. The experiment on anti-permeability of concrete and cellulose fiber concrete are made. And the rule of the anti-permeability of cellulose fiber concrete with the different content of fiber is researched. The factors of influencing the anti-permeability of concrete are analyzed. The experimental results indicate that the antipermeability of concrete is improved because of the cellulose fiber, and the permeability coefficient of concrete decrease with the increasing of content of fiber. Even the content of fiber is 0. 9 kg/m^3, the antipermeability of concrete is obvious improved.
