| 摘 要： | 从碳化理论模型出发,利用大量工程实测结果和气象调查资料,建立了以混凝土立方体抗压强度标准值为主要参数,考虑环境影响(环境温湿度)和CO2浓度影响的平均碳化深度预测模型,进一步考虑碳化过程的随机性,提出了预测混凝土碳化深度的随机模型。最后,用工程实测数据对模型进行了验证分析。

| Abstract: | Based on the theoretical model of carbonation and analysis on plenty of spot data and weather data, the model of predicting average carbonation depth is proposed This model takes the compressive strength of concrete as the main parameter, and considers influence of temperature, moisture , and concentration of carbon dioxide Taking into account the randomicity of the carbonated process, the random model of predicting the carbonated concrete depth is presented in the basis of the preceding model At last, this random model is validated by spot date |

| Keywords: | carbonation of conerete random model compressive strength of concrete influence of environment |
