| 摘 要： | 本文主要介绍一种新型的混凝土氯离子扩散系数快速测定方法——RCM法。对其工作原理及测试方法进行了评述。并测定了氰离子在一系列不同水灰比的混凝土中的扩散系数，结果表明，混凝土的抗氯离子渗透扩散能力随水灰比的减小而提高。

| Abstract: | A new rapid testing method for determining chloride ion diffusivity in concrete called RCM is described. With this testing method, the effect of water-cement ratio on the chloride ion diffusivity was studied. Test results indicate that the resistance of concrete to chloride ion penetration increasing with the decreasing of water-cement ratio. |

| Keywords: | concrete chloride ion non-steady state diffusivity |
