Effects of Blended Steel Slag-Superfine Fly Ash Mineral Admixture and Ordinary Fly Ash on the Properties of Concrete
The effects of blended steel slag-superfine fly ash mineral admixture and ordinary fly ash on the properties of concrete were compared in this study.The results show that,in the case of the same adding amount,blended steel slag-superfine fly ash mineral admixture and ordinary fly ash have similar effects on the early strength and chloride ion permeability of concrete.Blended mineral admixture has higher ability to improve the late strength of concrete than ordinary fly ash.Paste and concrete containing blended mineral admixture have smaller porosities than that containing ordinary fly ash.Blended steel slag-superfine fly ash is an ideal mineral admixture for concrete.
