摘要
本文提出了一种快速预报水泥强度的方法.其特点是:仅仅利用水泥厂物理检验和化学分析的现成数据建立多元线性回归方程,而无须进行专门的快速试验;回归方程中可不包含水泥熟料的矿物成分,因而具有较广泛的适用性.研究结果表明,预报精度达到ZBQ11004-86《水泥强度快速检验法》的规定要求.
An approach for the rapid prediction of cement strength is presented In this paper.This approach is characterized by establishing multiplelinear regression equations using only the data of physical testsand chemical analysis provided by the cement factories withoutdoing any special on-the-spot test,and wider applicability sinceregression equations are independent of the chemical compositionof cement clinker.The results show that the prediction precisionmeets the requirements of ZBQ11004-86Accelerated Test for CementStrength
