基于矿渣+粉煤灰的透水混凝土性能试验研究

Experimental Research on Performance of Pervious Concrete Based on Slag+Fly Ash

根据对不同配合比掺和矿渣+粉煤灰透水混凝土试件的实验数据相比较,采用正交试验方法,分析水胶比、矿渣、粉煤灰三个因素对透水混凝土的抗压强度、透水性能的影响。通过实验筛选分析得出性价比高的矿渣、粉煤灰双掺透水高强度混凝土最佳配合比:水7.3%、胶凝材料18.9%、矿渣3.3%、粉煤灰1.4%、砂21.4%、卵石52.4%。

Based on the comparison of experimental data of slag+fly ash permeable concrete specimens with different mixing ratios,the orthogonal test method was used to analyze the compressive strength of water-binder ratio,slag and fly ash to permeable concrete Influence of strength and water permeability.Through experimental screening analysis,the best mix ratio of cost-effective slag and fly ash double-permeable high-strength concrete:water 7.3%,cementing material 18.9%,slag 3.3%,fly ash 1.4%,sand21.4%,Pebble 52.4%.
