Influence of the Addition of Steel Slag and Fly Ash on the Properties of Cement

GUAN Zong-fu,YU Yuan-ming,WANG Yun-hao,CHEN Xiang-xiang (School of Materials Science and Engineering,Zhengzhou University,Zhengzhou 450001,China)  
The effect of the proportion and fineness of steel slag(SS),fly ash(FA) and types of gypsum on the properties of SSFAS composite cement were studied with orthogonal design experiment.The result shows that the fineness of FA is the key factor affected the strength.The match of SS and FA and the type of gypsum make the smaller effect on the strength compared with the fineness of FA.The optimal composite cement borne excellent overall properties,which program was given as follows: the proportion of SS and FA is 21∶9,the fineness of SS is 447 m2/kg,the fineness of FA is 400 m2/kg,the types of gypsum is 3 copies of natural gypsum and 2 copies of desulfurization gypsum.
