摘要
自收缩是引起混凝土早期出现裂缝的主要原因,因此自收缩的预测对于裂缝控制、抗裂计算和结构设计具有重要意义。本文介绍了国内外预测混凝土自收缩的模型并对其进行了分析和评价。
Autogenous shrinkage of concrete is often suspected to be the main cause of cracking in concrete at early age. So the prediction on autogenous shrinkage is of great importance for crack control, restraint calculation and structure design. Comparison, analysis and evaluation are made of various models which have been proposed to predict the Autogenous shrinkage of concrete in this paper.
