盐冻环境下混凝土结构耐久性提高措施研究

Study on measures of improving concrete structure durability under salt-freezing environment

根据盐冻环境下的混凝土结构破坏机理,从增大混凝土强度、增加结构的保护层厚度、防水处理、加入引气剂等方面,提出了盐冻环境下提高混凝土结构耐久性的措施,使混凝土结构达到预期的使用寿命。

According to the concrete structure damage mechanism under salt-freezing environment,starting from aspects of enlarging concrete strength,increasing structural protection layer thickness,waterproofing treatment and adding air-entraining agent,the paper puts forward measures of improving concrete structure durability under salt-freezing environment,so as to achieve expected service life of concrete structure.
