Therefore, in this paper, the mathematical theory and practice data illustrate the issued in advance concrete mix than the feasibility report, even concrete mix than that reported from 28 to 30 days in advance to 7 to 10 days and issue, which requires usually the accumulation of concrete mix ratio design of relevant data, under the different condition to establish the correlation equations between concrete 7 days compressive strength (R7) and 28 day compressive strength (R28). Only to establish the relevant equations in line with the actual situation, in order to determine its R7 according to the concrete R28, according to the rapid determination of more reasonable concrete mix.正文快照:一、理论依据本文用回归分析方法建立相关方程,即以X(R7)为可控变量,以Y(R28)为随机变量,在实际试验中,对X和Y作n次试验观察,并且假定在X的各个值上对Y的观察是相互独立的试验值,经过数学推导,其相关方程和相关系数的计算公式如下:可控变量X与随机变量Y的密切程度用相关系数R分享到:相关文献|
