混凝土成熟度法预测早期强度在联锁片施工中的应用

介绍了混凝土成熟度的概念、原理以及发展过程,阐述了混凝土成熟度原理在联锁片施工中的应用方法,根据收集的试验数据建立了强度关系式并进行数据分析,即用计算法、图解法等方法估算混凝土的早期强度,以达到在预制构件施工特别是冬期施工时能够及时拆模、起吊,达到加快模板周转、提高施工效率,当联锁片采用人工加热养护时能够实时估算构件的即时强度,判定是否需要继续供热达到节约能源之效果。

Application of concrete maturity theory in predicating early strength of concrete in construction of interlocking pieces

This paper introduces the concept,theory and development of concrete maturity,expounds the application method of concrete maturity theory in the chain construction,and sets up the strength formula by collecting experimental data to estimate the early strength of concrete by the calculating method and graphical method.By this method,we can remove the form and crane the prefabricated part timely,especially in the winter.We can not only speed up the revolution of the module,but also improve the efficiency by this theory.When maintaining the prefabricated parts by artificial heating,we can estimate the immediate strength of the parts.This can help us determine whether we should heat the parts,which can save energy.
