摘　　要：采用RCM氯离子扩散系数法和渗水高度法,研究了粉煤灰、矿粉、PVA纤维、纤维素纤维的掺入对混凝土抗渗性能的影响。试验结果表明,粉煤灰和矿粉的掺入能有效降低混凝土中氯离子扩散系数和渗水高度。在掺加矿物掺合料的基础上再掺入纤维混凝土的抗渗性能进一步提高,双掺对混凝土抗渗性能提高的复合效应明显。The influences of fly ash, slag, PVA fiber and cellulose fiber on the penetration resistance of chloride ions into concrete are studied, through using the chloride ions diffusion coefficient test method （RCM） and depth of water penetration test method. The experimental results show that the addition of fly ash and slag can effectively reduce the chloride ion diffusion coefficient in concrete and water seepage height. Mineral admixture concrete mixed with fibers can further improve the impermeability of concrete, and combined admixtures of mineral admixtures and fiber can obviously improve the impermeability of concrete.
