Abstract: In this contribution, the influences of the additives of calcic, silicic and aluminium materials on the reconstructed steel slag were investigated by the orthogonal experiment. In the experimental program, the optimum dosage of additives was determined. The composition of mineral phase was analyzed by XRD and the appearance of minerals was observed by SEM. The results show that the optimum dosages of additives are, the calcic material is 8.85%, the silicic material is 2.48% and the aluminium material is 2.79%. Because more cementitious minerals the reconstructed steel slag has better cementitious property. When the cementitious minerals react with water, more hydration products would be produced, the harden paste would become denser, and the strength of harden paste would be higher than steel slag.
