Abstract: Some main carbonation models of concrete with multi-factors are analyzed comparatively. Through combination of the recent research and the existent models, an improved model involing the environment factors and the density of CO2 is presented. The results of it match the tested engineering data better. Further more, some conclusions and suggestions are made in the end

Key words: carbonation of concrete, durability, depth of carbonation.

摘要： 较系统地阐述了现有的多因素砼的碳化模型，并对它们进行了分析比较，结合最新的研究动态，提出了考虑 环境因素和CO2浓度因素的碳化深度预测模型，用工程实测数据对模型进行了验证，同时指出了砼碳化方程模型 需要改进的地方
