摘　　要：混凝土的渗透性决定了气体、液体以及可溶性有害物质侵入混凝土的难易程度,直接决定着混凝土的碳化、侵蚀、钢筋锈蚀和抗冻融性能,是影响混凝土结构物耐久性最重要的因素之一。基于不同的传输过程,系统地阐述了混凝土材料的渗透性试验方法,比较了不同试验发展进程和各自特点;并给出了今后混凝土材料渗透性试验的研究方向。It is one of the important factors with penetration to the durability of concrete materials, as it affects the transmission of gas, liquid and other ions, which determines the properties in concrete of carbonization, corrosion and so on.The methodology of penetration measurement for concrete materials is discussed systemically based on different transfer process.And their characteristics are compared with the test procedure. Moreover, the development of penetration measurement for concrete materials is indicated.
