摘　　要：分析了影响混凝土抗渗性能的各种因素,为验证碳纤维能提高混凝土的抗渗性能,通过制备碳纤维混凝土抗渗试件,并对试件施加水压力,研究影响抗渗的各种因素及其影响规律,得出了当碳纤维掺量达到0.6%时,混凝土抗渗性能提高最显著,碳纤维长度为10mm时,混凝土抗渗性能最好,当纤维掺量低于0.2%时,水灰比对混凝土的抗渗性能影响较明显,当纤维掺量超过0.2%时,水灰比对混凝土的抗渗性能影响较小。This paper analyzes various factors which impact the impermeability of concrete.Through the preparation of carbon fiber reinforced concrete specimens and the exertion of water pressure on these specimens,it is proved that carbon fiber can improve the impermeability of concrete.When the carbon fiber content reaches 0.6%,the impermeability of concrete improves most significantly.When the carbon fiber length is 10mm,the impermeability of concrete is best.When the fiber content is less than 0.2%,the water-cement ratio influences the concrete impermeability more significantly.When the fiber content is more than 0.2%,the water-cement ratio has less influence on the concrete impermeability.
