Research on the Performance of Metallurgical Slag All Solid Waste Cementitious Materialin Concrete
By adjusting the amount of steel slag in the proportion of cementitious materials,solid waste based high performance concrete(C30,C40,C50)with different strength grades was prepared,and the influence of different steel slag content on the performance of concrete was studied.The experimental results have shown that solid waste based concrete has good workability and strength when the steel slag content is between 10%and 15%;When the steel slag content is 15%,the best carbonization resistance reaches T-IV level;When the steel slag con-tent is 10%,the best resistance to chloride ion penetration and frost resistance are achieved,reaching Q-V and F275 levels,respectively.
