Effect of Co-Doped Steelmaking Slag and Fly Ash on Performance of Permeable Concrete

Abstract:

The effect of steelmaking slag and fly ash as multi additives on permeability and mechanical properties of permeable concrete was investigated. The results show that multi binder with fly ash, steelmaking 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 (15 wt.% ) and steelmaking slag (10 wt.%), good mechanical properties and high permeability coefficient were obtained. Fly ash and steelmaking slag has a micro-aggregate filling effect on the concrete interface.
