【摘要】 混凝土结构钢筋腐蚀是影响结构耐久性和安全性的重要因素之一。根据混凝土结构钢筋腐蚀机理 ,认为抑制钢筋腐蚀 ,应控制好混凝土保护层厚度、氯离子含量和混凝土裂缝宽度 ,并应采取有效措施提高混凝土的密实性、掺入引气剂、合理选择饰面材料等。更多还原

【Abstract】 Rebar corrosion in concrete structure is one of important influence factors for durability and security of structure .Based on the mechanisms of rebar corrosion in concrete structure, the author considers that reinforcement cover thickness, chlorion content and crack width should be controlled if restraining rebar corrosion; and the compactness of concrete should be enhanced by applying efficient measures,mix with air-entraining admixtures,select facing materials and so on.更多还原
