摘要
高寒地区处于经常潮湿积水部位的混凝土结构,受冻融破坏产生酥碎掉渣现象非常广泛,从而使混凝土结构过早丧失了安全、耐久及使用性功能。从混凝土冻融产生酥碎掉渣机理,以及影响混凝土抗冻融循环因素等方面进行分析,并对抗冻性混凝凝土从试验数据方面进行了统计与探讨。
The concrete structure in the area of frequent damp water in the cold area,the freeze-thaw damage produced crisp residue phenomenon is very extensive,So that the premature loss of concrete structure safety,durability and functionality.Therefore,from the concrete freezing and thawing mechanism of crisp dregs;the factors that affect the freeze-thaw resistance of concrete are analyzed,In addition,the experimental data are analyzed and discussed in this paper.
