混凝土的渗透性与混凝土的耐久性紧密联系,是评定混凝土耐久性的一个重要指标.渗透性控制着水、气体以及其他侵蚀性离子在混凝土中的传输速率,表征混凝土的渗透性可以通过不同介质来测定.文章综述了目前各种渗透性测试的方法、适用条件及优缺点,指出研究三种渗透性表征方法之间相关性的必要性.
Permeability of the concrete works closely with the durability of concrete. It is an important indicator for assessing the durability of concrete. Permeability controls the water, gas and other aggressive ions in concrete transfer rates. Characterization of concrete permeability can be measured by different media. This paper reviews the current penetration testing methods, applicable conditions, advantages and disadvantages, and notes the necessity of correlation of the three permeability methods.
