混凝土水灰比公式中回归系数的研究

Concrete Water-Cement proportion the Coefficient in Formula is Discussed

为了寻求与普通混凝土配合比设计规程中的回归系数之间的差异,探讨回归系数的变化对混凝土强度的影响,达到有效地节约原材料,更好地控制混凝土质量的目的,按照混凝土强度等级的不同做了大量试验,得出原始数据,对数据进行分类回归分析,建立了适合本地区的混凝土水灰比公式回归系数并对系数进行了讨论。

To seek , discuss the change of formula coefficient with ordinary concrete water-cement proportion the discrepancy between population in design specification, reach for the influence of concrete strength, economize raw material efficiently, control the purpose of concrete quality better, make plenty of experiments according to the difference of the grade of concrete strength, reach original data, classify for data, regression analysis have established the concrete water-cement proportion formula that suits local region , discuss formula coefficient.
