【摘要】 在分析了冻融与除冰盐共同作用下混凝土破坏机理的基础上,进行了清水、传统除冰盐溶液(3%N aC l溶液)和新型除冰盐溶液(3%C aC l2溶液)条件下的混凝土冻融循环试验研究。结果表明,除冰盐加快了混凝土的冻融破坏,但新型除冰盐对混凝土的冻融破坏影响小于传统除冰盐,一定程度上可以缓和盐冻破坏。更多还原

【Abstract】 On the basis of the analysis of the damage mechanism of concrete under the cooperation of freeze-thaw and deicing salt,the concrete freeze-thaw experimental researches have been done under the conditions of pure water,traditional deicing salt solution（3%NaCl solution） and advanced deicing salt solution（3%CaCl₂ solution）.The results indicate that the deicing salt accelerates the freeze-thaw damage of the concrete,while the advanced deicing salt influences less to the freeze-thaw damage of the concrete than the traditional deicing salt does and at the same time it can alleviate the salt freezing damage to some extent.更多还原
