摘要：

为了探寻“PERMIT”离子迁移方法与现行标准推荐方法的关系，对不同胶凝材料体系混凝土分别进行了
“PERMIT”离子迁移试验及RCM 快速氯离子迁移试验。通过对“PERMIT”阳极室溶液进行定量分析，发现胶凝材
料体系变化对阳极室溶液浓度变化率与电导变化率关系影响不显著，进而建立了两者的普适关系。试验结果表明，
“PERMIT”离子迁移测试结果与RCM快速氯离子迁移试验结果存在良好的线性相关关系，在此基础上建立了“PER原
MIT”离子迁移方法与RCM 快速氯离子迁移方法的关系。研究成果可简化结构混凝土抗氯离子渗透性现场测试步
骤，并使测试结果与现行标准推荐方法建立定量联系。

In order to explore the relation between PERMIT ion migration test and the method recommended in current
standard，concrete samples with different cementing materials are made to perform PERMIT ion migration test and RCM rapid
chloride migration test respectively. The results of quantitative analysis of anolyte of PERMIT ion migration test show that the
relationship between chloride concentration and conductivity of anolyte varies little with different concrete types. Then a
universal relationship between changing rate of chloride concentration and conductivity of anolyte is established. Based on the
testing results，a linear correlation between the chloride diffusion coefficients determined by RCM test that is an "index" test in
laboratory and PERMIT test is proposed. Based on the research results, the testing process of chloride ion permeability
coefficient of structural concrete can be simplified，meanwhile，the coefficient obtained by PERMIT ion migration test can be
correlated with the method recommended by the current standard.
