钢筋锈蚀对混凝土结构的危害及其预防措施

Research on damage of reinforcement corrosion to concrete structures and related prevention measures

钢筋锈蚀是造成混凝土结构耐久性损伤的最主要和最直接因素,也是混凝土耐久性破坏的主要形式之一。本文论述了钢筋锈蚀的机理,影响锈蚀的因素及其对混凝土结构的危害,最后提出了预防钢筋锈蚀应采取的有益措施,为减少锈蚀危害、提高结构的耐久性和安全性提供了重要依据。

Reinforcement corrosion is one of the most important and direct factors that lead to the durability damage of concrete structures.In this paper,the mechanism and influencing factors of reinforcement corrosion are described,as well as its harmful effects on concrete structures are discussed.Finally,somen effective measures for corrosion prevention are put forword which provide useful reference for the enhancement of structural durability and safety.
