粉煤灰混凝土力学性能的多元回归分析

以水胶比、粉煤灰掺量、水泥掺量为参数,配置8组混凝土试件,分别对其进行了抗压强度和抗折强度的试验。利用多元线性回归分析理论建立了混凝土抗压强度、抗折强度与水胶比、粉煤灰掺量、水泥掺量各因素之间的线性回归方程,并对计算结果进行显著性分析,从而建立了混凝土抗压和抗折强度的预测模型。

Fly Ash Concrete Mechanical Properties of Multiple Regression Analysis

In this paper,water-cement ratio,the amount of fly ash,cement content for the parameters,configured 8 groups of concrete specimen,and tested its compressive strength and the bending strength.Using theory of multiple linear regression analysis,then established the linear regression equation which reflected relationship between the compressive strength of concrete,bending strength and water-cement ratio,the amount of fly ash,cement content.In the end,proceed significant analysis according to the calculation of final results.So as to establish prediction model of concrete compressive strength and the bending strength.
