严酷环境下的混凝土耐久性进展研究

Review of the research progress about concrete durability under severe conditions

混凝土结构的耐久性是当今国内外进行大规模建设工程的重大课题。文章综述了冻融循环以及氯离子侵蚀两种因素对混凝土耐久性的影响,讨论了冻融循环以及氯盐腐蚀的研究背景以及破坏机理,指出此课题研究的重要性。

Concrete durability has been an important issue at present. A review is given on the effect of freeze-thaw cycles and chloride ion erosion on concrete durability. Moreover, the research background and damage mechanism are disscussed, which points out the importance of the research subject.
