去冰盐破坏混凝土结构的机理及预防措施

Destruction Mechanism of the Deicing Salt on Concrete Structures and the Preventive Measures

从材料层次上分析了去冰盐对混凝土结构的破坏机理及破坏特征 ,并提出了采用引气剂、控制水灰比、选用矿物掺合料和骨料等综合应用的抗冰盐剥蚀预防措施 .

The mechanism of the destructive effects of deicing salt on concrete structures is explored chemically and physically.The suggested anti erosion preventive measures include:to employ degassers,to control the water cement ratios,to mix in mineral admixtures and skeletal materials,and the combinations of the above measures.
