摘要：
A steel slag cement manufactured by reducing a steel slag discharged from a steelmaking furnace such as a converter, an open-hearth furnace or an electric arc furnace, and then oxidizing the steel slag thus reduced, which consists of, in weight percentage:CaO : 68 to 72%,SiO.sub.2 : 22 to 26%,Al.sub.2 O.sub.3 : 1 to 3%,Fe.sub.2 O.sub.3 : 0.2 to 1.0%,P.sub.2 o.sub.5 : 0.1 to 0.6%,TiO.sub.2 : 0.4 to 0.9%,MnO : trace to 0.4%,MgO : 0.3 to 3.0%,CaF.sub.2 : 0.3 to 2.0%,and the balance incidental impurities.
