氯盐类融雪剂对混凝土路面危害分析

The analysis of chloride deicing salts' hazard on concrete pavement

氯盐类融雪剂在我国北方地区有着广泛的使用,但在使用过程中,存在对融雪剂的腐蚀性认识不足,缺乏相应产品标准和使用规范等问题。本文对融雪剂的类型进行了介绍,对氯盐类融雪剂对混凝土路面的腐蚀机理进行分析。通过冻融循环实验,研究了几种常见氯盐类融雪剂的腐蚀特性,并得出实验结论。

Chloride deicing salts has been widely used in northern China, but the corrosion of deicing salt usually has been neglected during the use, and there is a lack of the appropriate product standards and the use of norms. In this paper, types of deicing salt are introduced;deicing salts of chlorine on the corrosion mechanism of concrete pavement are analyzed. By freeze-thaw cycle experiments, the corrosion properties of several common chloride deicing salts has been studied, and the conclusions of the experiment has been drawn.
