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 . |

Keywords: | permeable concrete steel slag fly ash |
