摘要
对近年来混凝土冻融及盐冻破坏机理的研究进展及成果进行了总结,评述了孔结构、水灰比及外掺料对混凝土抗冻性及抗氯盐冻融性能的影响,同时总结了混凝土冻融劣化模型的研究进展。在此基础上为混凝土冻融及盐冻劣化的进一步研究方向提出了建议。
The research development of mechanism and mathematical model for salt scaling damage and freezing-thawing damage of concrete was summarized.The effect of pore structure, water-cement ratio and admixtures that had on the salt scalingand freezing-thawing resistance of con- crete was observed and the research development offreezing-thawing deterioration model of concrete was summarized.On this basis, the further di- rection for salt scalingand freezing-thawing deterioration of concrete research was recommended.
