氯盐环境下混凝土耐久性研究进展

Progress of Durability of Concrete Under Chloride Environment

氯盐环境下混凝土结构的耐久性是沿海地区混凝土结构的一项关键指标,直接影响其正常使用寿命。从环境、材料、构件及结构4个层次系统论述了氯盐环境下混凝土耐久性的研究成果。分析认为当前的研究成果仍无法直接应用到实际工程中,还需继续研究。氯离子侵蚀环境和试件本身的受力状态应作为今后研究重点考虑的因素。

Durability of concrete under chloride environment is a key index in coastal regions and it can directly influence the service life of concrete structures. The study achivements are summarized from environment, materials, components and structures respectively. The conclusion is that the study achivernents cannot be directly applied to engineerings and chloride environment and stress state of concrete should be highly considered.
