Experimental study of the soundness and compatibility of Baosteel steel-slag powder applied in cement concrete

To reduce the cost and improve concrete performance, massive admixtures were needed to be added to the concrete. With the research going, the high quality mixture is increasingly becoming the indispensable concrete component. The steel slag powder is the steel-slag comprehensive utilization technical commanding point compared with the level of the steel slag application nowadays in the world. In order to develop the application of the steel slag fine powder in cement concrete domain, this article analyzes autoclaved soundness of the Baosteel steel-slag fine powder as well as the compatibility of it with the cement and the concrete admixtures.
