摘要
水泥混凝土结构因耐久性不良造成过早失效及崩塌破坏的事故时有发生,世界各国为此造成了很大的损失。综述了国内外有关水泥混凝土腐蚀的研究现状,包括腐蚀因素、腐蚀机理、腐蚀过程的研究与分析成果;总结了提高水泥混凝土腐蚀能力的技术措施,如改变水泥熟料矿物组成、添加掺合料、提高密度、表面涂料防护等等。最后,提出了未来的主要研究方向。
Collapse accident occurs frequently because of poor durability of concrete structure, which caused great loss to all countries in the world. And the research state of concrete corrosion in domestic and oversea including corrosion factor, mechanim and prosess was summarized as well as the measures of improving the corrosion resistance of cement concrete as adjusting eliker mineral component, adding admixture, increasing the consistency and surface protective coating. Finally, the main research direction in the future was brought forward.
