摘要
设计了三因素三水平正交试验,测定了透水混凝土标准试件的透水系数和抗压强度,采用直观分析、方差分析和层次分析,得到了最佳配合比:水灰比0.30、骨料粒径10 mm^15 mm、目标孔隙率25%。
Three factors and three levels of orthogonal experiment were designed. The permeability coefficient and compressive strength of standard permeable concrete specimens were measured. The optimal mixture ratio was obtained by visual analysis,variance analysis and hierarchical analysis: water cement ratio 0. 30,aggregate size 10 mm ~ 15 mm,target porosity 25%.
