RCM法测试混凝土氯离子渗透扩散性

RCM testing the penetration and diffusion of chloride ion in concrete

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,并测定了氯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。

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.
