摘　　要：通过对两种不同纤维掺量的混凝土试件和普通无纤维混凝土试件抗渗试验的对比,研究了水泥基纤维混凝土的抗渗机理及性能特点,发现掺入改性聚丙烯纤维后混凝土抗渗性能的改善效果与纤维掺量有关,在一定范围内,掺量越大,效果越佳,但同时会降低混凝土的坍落度。Research was made on the impervious mechanism and character of cement-based fiber concrete through the impervious test comparison between 2 concrete samples of different fiber admixing amounts and common non-fiber concrete. It is found out that the improvement effect of the anti-seepage behavior of the concrete admixed with modified polypropylene fiber is related to the fiber amount admixed, within certain scope, the more the amount, the better the effect but meanwhile, the concrete slump reduces accordingly.
