摘要
碳化和氯离子是引起混凝土结构中钢筋锈蚀的最主要原因,通过分析碳化的发生机理和影响因素及混凝土中氯离子的来源和诱发钢筋锈蚀的机理,论述氯离子在混凝土中扩散的Fick定律和提高混凝土结构耐久性的措施。
Carbonation and chloride are the most important reasons which caused steel corrosion in concrete structure.The mechanism of carbonation occurrence and effect was analyzed.The chloride source in concrete and corrosion mechanism were introduced.The Fick model which proposed the chloride diffusion in concrete was stated.Measures improving concrete structure durability were offered.
