| 摘 要： | 应用正交试验设计,设计9组高性能混凝土。正交试验为三因素三水平,选取L9(34)正交表。三因素三水平分别为搅拌(人工搅拌,机械搅拌,超时机械搅拌)、振捣(人工振捣,机械振捣,免振捣)及养护(自然养护,标准养护,绝湿养护)。针对该9组混凝土冻融循环试验,对试验结果进行正交试验的级差分析及方差分析。

| Abstract: | 9 groups of high performance concrete(HPC) have been designed with orthogonal experimental design,in which there are 3 factors and 3 levels.The orthogonal experimental design table is L9(34).The factors and levels are mixing(artificial mixing,mechanical mixing,overtime mixing),vibrating(artificial vibrating,mechanical vibrating,vibration-free) and curing(natural curing,standard curing,humidity insulation curing).Freezing-thawing tests of these HPC have been carried out,and then differential analysis and var... |
