摘要
在已有碳化模型的基础上,利用大量工程实测结果和现有研究成果,考虑混凝土碳化过程的随机性,建立了包括结构受力状态、环境温度、湿度、混凝土质量和CO2浓度影响的预测混凝土碳化深度的随机概率模型。最后,通过工程实测数据对模型进行了验证分析。
On the basis of existing models for concrete carbonation, the authors in this paper establish a new random probability model for predicting concrete carbonation depth under influences of various factors like the structure mechanical conditions, ambient temperatures, humidity, concrete quality and CO2 thickness, using plenty of field measurements, current research findings of concrete construction and taking into account of random in course of the carbonation, and the authors also analyze and verify the model in compliance with the data of the field measurements.
