氯盐对混凝土中钢筋的腐蚀机理与防腐技术

Chemical mechanism and prevention technologies of chloride-induced reinforeement corrosion in concrete

钢筋锈蚀是引起混凝土结构破坏的主要原因 ,而大多数情况氯盐腐蚀是钢筋腐蚀的首要因素。本文以钢筋腐蚀为主线 ,分析阐述了氯盐对混凝土中钢筋的腐蚀机理 ,指出了相应的防护技术措施 ,并着重讨论了氯盐环境对高性能混凝土防腐的技术要求 ,介绍了近

Reinforcement comosion is a main cause for stmctme destruction alldit is substalttially due to the chloride in many instances. Taking reinforcementcomosion as a key, this paper summaries the chemical mechallism of chloride induced reinforcement comosion, presents a several new preventiontechnologies and gives the technical requirements for high durable concrete andconcrete speci8cations for 2 bridge buildings completed in last 5 years. 〔
