硫酸盐侵蚀环境因素对混凝土性能的影响——研究现状综述

The effect of sulfate as an environmental factor on the concrete deterioration:

硫酸盐侵蚀是影响混凝土耐久性的一项重要因素,在实际工程中混凝土材料往往处于不同的硫酸盐环境中如不同浓度、不同温度以及干湿循环等等,本文系统地阐述了国内外关于环境因素对硫酸盐侵蚀混凝土的研究现状,总结了已有的研究成果并结合最新的研究动态指出该研究中存在的若干问题,为以后的研究提出了一些建议。

Sulfate attack is one of the most important problem on concrete durability,in fact,the sulfate environment of concrete existed is different,such as different concentration of SO^(2-)_4,different temperature and dry-wet circulation etc.The present research of the effect of environmental factor of sulfate on the concrete deterioration is systematic elaborated.The existed research outcome is remarked,the problem existed in the research is pointed out,and the prospects of sulfate attacked concrete are proposed.
