钢筋混凝土构件碳化规律研究
|
摘要
在大量工程实例调查的基础上 ,分析了各种环境下工业厂房钢筋混凝土构件的碳化规律 用碳化速度系数和碳化强度系数的概念 ,提出了碳化深度、标准差以及碳化后砼强度的预测模型 ;并针对各种环境下混凝土构件碳化的规律提出对策
Based on the investigation of enormous practical engineering instances,the carbonation regularity of reinforced concrete component of milling buildings in all sorts of circumstances was analysed.With the definition of carbonation velocity quotients and carbonation strength quotients,the prediction models of carbonation depth and standard deviation and carbonation concrete strength are presented.Aiming at the regularity of concrete carbonation of reinforced concrete component in all sorts of circumstances,the countermeasures are proposed.
