摘要
本文以水胶比、粉煤灰掺量、砂率为参数、配制18组自密实混凝土,并进行基本力学性能试验,最后利用多元线性回归分析方法建立自密实混凝土抗压强度、劈拉强度、弹性模量与水胶比、粉煤灰掺量、砂率各因素之间的线性回归方程,对计算结果进行了显著性分析。从而建立了自密实混凝土抗压强度、劈拉强度、弹性模量等力学指标的预测模型。
In this paper, to Discussed the affecting factors of compressive strength, splitting tension strength, elastic modulus with the percentage of sand, water binder ratio, volume of fly ash .eighteen groups of Self-Compacting Concrete were done.Using multivariate regression analysis, the empirical formula of compressive strength, splitting tension strength, elastic modulus with the percentage of sand, water binder ratio, volume of fly ash were put forward.
