摘要
盐污染环境中由于氯化物引起钢筋腐蚀导致钢筋混凝土结构过早破坏,是世界上普遍存在的现象。对新建钢筋混凝土结构进行阴极极化以预防腐蚀的方法称为钢筋混凝土阴极防护技术。介绍阴极防护与阴极保护的异同,对阴极防护中保护准则和防护系统寿命进行了初步探讨,为钢筋混凝土阴极防护技术有效合理应用提供参考。
It is the most common phenomenon that reinforced concrete structures suffer premature deterioration from chloride induced reinforc-ing corrosion in chloride salt environment.The method of applying cathodic polarization to prevent corrosion of newly-built reinforced concrete structure is called cathodic prevention.It mainly introduces the difference between canthodic protection and cathodic prevention,and preliminarily studies protection criterion of cathodic prevention and service life of protection system,which provide references for the reasonable application of cathodic protection for reinforced concrete.
