复掺钢渣和粉煤灰对透水混凝土性能的影响

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。

Effect of Co doped Steel Slag and Fly Ash on Performance of Permeable Concrete

The effect of steel slag and fly ash additive on permeability and mechanical properties of permeable concrete is investigated. The results show that the multi binder with fly ash, steel slag and cement has a significant 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 concrete interface.
