Abstract

Modified steel slag was prepared by mixing molten fly ash and steel slag at high temperature.We have studied its microscopic structure and macroscopic mechanical properties.The results showed that:The content of the fCaO was decreased by adding modified steel slag;The strength of the modified steel slag cement is a little lower than the ordinary one,but the strength was still meeting the need of P.SS32.5R cement.It is feasible that modified steel slag can become one of the cement materials.
