氯腐蚀环境混凝土中钢筋腐蚀速度及腐蚀过程分析

Analyses on the Corrosion Speed and Process in Reinforced Concrete Corrosion by Chlorion

根据国内外的研究成果,结合工程验证资料提出了含氯环境下,混凝土中钢筋在保护层开裂前后的腐蚀速度计算公式,并对构件在腐蚀过程的各阶段建立了预测模型,利用国内外的实测资料验证了分析模型的可用性。

Based on the research results of investi^tion at home and abroad and the engineering data, this paper raises the eorrision speed calculation formulas of the reinforced steel in the concrete under the environment of cldorion before and after the breakage of the protection layer. The forecast model of the corrosion process is set up and the fesibility of the model is also tesitified.
