摘要
根据实验室内进行的人工砂混凝土和人工砂粉煤灰混凝土配合比试验结果,采用线性回归统计分析了人工砂混凝土和人工砂粉煤灰混凝土强度与水灰比的关系,求出αa,αb系数.并用于工程实践证明其可行.
Based on the tests in laboratory on the concrete composed of manufactured sand and fly ash, the relationships of the strength of concrete and the binder to water ratio are analyzed by the method of liner regression and the coefficient values of aa and ab are determined respectively. These formulas are demonstrated by engineering data.
