A Experimental Study on the Influence of Fly Ash, Slag Powder on the Property of Concrete

In this paper, the role of fly ash and slag powder on the concrete are introduced. Through the experiments that mixing up fly ash , slag powder or two kinds of mineral admixtures in the concrete, the characteristics of property of concrete at different times are learned. The results show that the property of concrete are better when two kinds of mixtures are used than mixing one of them, and the most appropriate proportion of mixing is 30%~40%.
