| 摘 要： | 来自海洋环境和除冰盐的氯化物，使混凝土在冬季处于氯盐介质条件下的冻融循环，在这种冻融循环作用下混凝土更易产生剥蚀破坏，从而降低了混凝土的耐久性。分析了混凝土在氯盐介质下冻融破化的物理、化学机理和破坏特征，并根据破坏机理提出了预防混凝土盐冻破坏的措施。

| Abstract: | Chloride coming from ocean and deicing salts made the concrete under the action of chlorine salts' freeze and thaw cycles in winter.Under this kind of condition,concrete was easier destructed,and durability of concrete was decreased.Base on the research of experiment and literature,this paper summarized the freeze and thaw destruction's physics and chemistry mechanism of concrete under the condition of chlorine salts,destruction characters,and put forward the prevented measures of freeze-thaw salt damage of concrete according to the mechanism. |
