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。
Starting from the carbonation theory model, using a large number of actual measurement results and meteorological survey data, an average carbonation depth prediction model based on the standard values of concrete cube compressive strength as the main parameter, taking into account the influence of environmental impact (ambient temperature and humidity) and CO2 concentration, was further developed. Considering the randomness of the carbonization process, a stochastic model for predicting the carbonation depth of concrete was proposed. Finally, the model was validated and analyzed using actual measured data.
