混凝土碳化分析及其耐久性预测研究

混凝土碳化深度值是评价钢筋混凝土结构耐久性的一个重要指标,本文论述了混凝土碳化深度的影响因素,概述由理论推导和试验基础上拟合的碳化深度模型。混凝土中实际存在的碳化区、部分碳化区和未碳化区与理论的模型假设条件是不同的,由此造成的酚酞测试方法可能存在一定的局限性。

Analysis of Concrete Carbonization and Prediction of Concrete Durability

The depth of concrete carbonization is a vital index for evaluating the durability of the reinforced concrete. The influence factors of concrete carbonization and the model of carbonization depth based both on the theory and the experiential test data are expounded. The conditions of the carbonization zone, partial carbonization zone and uncarbonated zone are not same as the assumed conditions of the model. Thus, the limitation may exist in the phenolphthalein test.
