根据正交试验设计C50微膨胀混凝土配制实验,将用灰关联分析法(Grey Relation Analysis,简称GRA)对试验结果进行分析,并与传统的直观分析法进行对比。应用GRA对不考虑交互作用的正交试验结果进行统计分析,得出各因素各水平对试验结果的关联度,从而确定因素的主次顺序以及最优试验条件。
According to the experiment design of C50 micro-expansive concrete by orthogonal experiment, the gray relation analysis (GRA) is used to analyze the test results and compared with the traditional visual analysis method. By using GRA, the orthogonal test results without considering the interaction were statistically analyzed, and the correlation between each level and the test results was obtained, so as to determine the order of the factors and the optimal test conditions.
