| 摘 要： | 研究了复合引入炼钢废渣和粉煤灰对透水混凝土性能的影响，并对透水混凝土的透水系数和强度进行了分析。结果表明：粉煤灰、钢渣和水泥作为胶结料复合使用，对各物料的水化反应起到促进作用。当粉煤灰掺量为15％、钢渣掺量为10％时，透水混凝土28 d抗压强度和透水系数均较高。粉煤灰和钢渣复合加入，使胶结料连接桥更致密，强度更高。

| Abstract: | The effect of steel slag and fly ash additive on permeability and mechanical properties of permea -ble concrete is investigated .The results show that the multi-binder with fly ash , steel slag and cement has a sig-nificant impact on the permeability and compressive strength of permeable concrete specimen .When the co-doped admixture is added with fly ash （ wt.15%） and steel slag （wt.10%）, good mechanical properties and high permeability coefficient are obtained .Fly ash and steel slag has a micro-aggregate filling effect on the con-crete interface . |
