多元回归分析评价粉煤灰混凝土的研究

Research on Appraisement of Flyash Concrete Using Multivariate Regression Analysis

用多元回归方法对掺用粉煤灰和外加剂后工厂实际生产混凝土各种构件的各种生产配合比,以及实验室各种配合比进行了分析评价.用回归方程分析诸因素对蒸养出窑强度和28天抗压强度影响的变化规律十分有益.

Various mix-proportion in actual production,in which the concrete products mix with flyash admixtures,are appraised by multiple regression analysis,and various mix-proportion in laboratory are also appraised by the same way.The regression equation is quite of benefit to analysing the transformation law which is about the effect of multiple factors on early steam strength and 28 days strength. Therefore,the equation is the foundation for further predicting and controlling the quality of flyash concrete,as well as seeking after the best conditions of production technology.
