摘要
砼碳化及钢筋锈蚀导致钢筋砼构件耐久性能降低。特别是在部分工业建筑中 ,由于二氧化碳浓度较高 ,环境恶劣 ,所以砼碳化深度加大、碱度降低 ,钢筋保护膜被破坏 ,最终导致钢筋砼构件过早破坏。就此进行理论分析 ,并提出在设计。
Concrete and reinforcement bar corrosion reduced the reinforced concretes' durability. Especially in some industrial buildings, the high content of carbon dioxide and the bad environment lead to greater concrete carbonization depth, low alkalinity and the destroy of concrete cover. A theoretic analysis was thus made concerning this problem. Technical measures adopted in both design and construction are presented. Problems in need of attention are pointed out.
