摘要
本文对酸雨区混凝土腐蚀机理及影响因素进行了总结,深入分析了在酸性介质中混凝土碳化作用、硫酸盐腐蚀、TSA腐蚀、镁盐腐蚀、Cl^-腐蚀和共存离子腐蚀的特征,介绍了酸性腐蚀下混凝土相应的防护措施和应用技术,以达到提高混凝土耐久性的目的。并提出了这方面工作尚待研究和解决的问题。
In this paper, Corrosion causes and mechanism of concrete in acid rain area is summarized. The corrosion character of carbonation, sulphate corrosion, TSA corrosion, magnesic corrosion, Cl^- corrosion, and form corrosion of coexist ions is analyzed and discussed in acid medium. Then introduce some protective methods and application technologies of concrete acid corrosion for enhancing the durability of concrete .and propose some question which should be study and solved in the future.
