摘　　要：混凝土的渗透性是决定耐久性的一个重要因素,本文分析了水渗透、气体渗透和氯离子渗透三种不同的渗透性测试方法的优缺点和使用范围,并提出了混凝土渗透性今后有待进一步研究的问题。The permeability of concrete is an important factor. Three different testing methods on permeability of concrete, including water permeability test, gas permeability test and chloride permeability test are studied. Each testing method has merits of its own, but each has its demerits. So each testing method can be used in some certain field. In addition, some problems of permeability that need further research in the future are pointed out.
