Abstract: Grind steel Slag through adding slag grinding improving the fineness of slag powder and activity, to achieve the objective of efficient use of steel slag .The results show that with the increase of the dosage of steel slag , the flexural strength of steel slag composite cement is downward trend after rising first, the highest bending strength when the dosage is 30％, 28 d compressive strength of steel slag composite cement plummeted , 3 d compressive strength first increased and then drop , the highest strength, when 30％proportion and up to 4.75 MPa.Combined with the actual economic benefits , and ultimately determine the ratio of steel slag composite cement clinker 65％, steel slag 30％, gypsum 5％, and grinding aid A works best when dosage of 0 .1％, fineness decreased by 49 .0％, and 28 d compressive strength increased 6 MPa.
