STATUS AND DEVELOPMENT OF CATHODIC PROTECTION AND CATHODIC PREVENTION FOR REINFORCED CONCRETE STRUCTURES
-
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。对已建钢筋混凝土结构进行阴极极化以控制腐蚀的方法称为钢筋混凝土阴极保护技术，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。主要介绍钢筋混凝土阴极保护和阴极防护技术的实施方法、状况与进展。Abstract: It is the phenomenon that concrete structures in salted contaminated environments suffer premature deterioration from chloride induced reinforcing corrosion.The method of applying cathodic polarization to the existing concrete structures for controlling corrosion is called cathodic protection.The method of applying cathodic polarization to the new concrete structures for preventing corrosion is called cathodic prevention.It is introduced that the construction method, status and development of cathodic protection and cathodic prevention for concrete.
