摘要
采用RCM法测定混凝土试件的氯离子扩散系数,研究表面砂浆层对混凝土抗氯离子渗透性能的影响。结果表明,致密的表面砂浆层能显著地降低混凝土本体的氯离子扩散系数。对强度等级低,抗氯离子渗透要求高的混凝土工程,采用表面砂浆层是非常有效的方法。
The effects of surface mortar layer on the resistance of concrete to chloride ion transport are studied in this paper, through obtaining the chloride ion diffusion coefficient of concrete specimens, by using RCM method. The experimental results show that surface mortar layer can significantly reduce the chloride ion diffusion coefficient of concrete. As far as the low strength concrete is concerned, surface treatment is a very effective method to improve its resistance to chloride ion penetration.
