【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.更多还原

【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.更多还原
