摘要
用成熟度推定混凝土强度,已为国内外所公认,但因影响的因素较多,故实际应用尚有一定困难。国内个别科研单位提出了混凝土成熟度系数。本文根据影响混凝土强度的诸多因素变化情况,在大量科学试验的基础上,提出了成熟度综合修正系数法及其计算公式,应用图表,并制定了应用技术规程,被批准为山西省地方标准。
The application of the maturity method for prediction of concrete strength has been widely recognized at home and abroad. It is still, however, difficult of application due to influence of a number of crucial factors. Some individual research institute in our country has introduced the concrete maturity method. In this article, it has been based upon the various key factors that affect the concrete strength such as kinds of cement consumed, and the various conditions of admixture etc. to overcome its difficulty. On the basis of large amount of scientific experimentation, it has introduced the maturity comprehensive amendment coeffi- cient method and calculation formula with its practical tabulations as well as its code and technical regulations., It has been approved as a local standard in Shanxi province.
