| 摘 要： | 氯化物是钢筋混凝土结构在正常使用寿命期内可能遇到的一种不利的侵蚀介质。混凝土中钢筋表面的氯离子浓度超过一定的限值,钢筋就可能会发生锈蚀;锈蚀的钢筋会导致混凝土构件的承载力下降。通过对国内外研究成果的总结,讨论了基于氯离子侵入引起的锈蚀钢筋混凝土构件的抗力计算模式,为氯盐环境条件下混凝土的耐久性评估提供参考。

| Abstract: | Chlorinate is an unfavorable attracted substance in reinforced concrete during its service. While the amount of chlorion on the surface of reinforcing steel bar exceeds the limited value, it could occur the corrosion on the reinforcing steel bar. The corroded steel bar may result in the decrease of bearing capacity of reinforced concrete member. Based on summarizing the research results about concrete structural durability, the model of resistance of reinforced concrete member corroded due to chlorion action is presented. It is useful to evaluate the durability of concrete structures. |
