Abstract

The iron tailing powder can increases fluidity of cement mortar because the fluidity ratio of iron tailing powder whose fineness is 340m2/kg is 105%, and the fluidity ratio of grinded iron tailing powder whose fineness is 680m2/kg is 120%. The strengths increase with increasing of iron tailing powder dosage, but when dosage exceeds 10% strength decreases; for grinded iron tailing powder, when dosage does not exceed 30%, strength increases; when dosage is same, grinded iron tailing powder can increase strength more than iron tailing powder. When dosage of iron tailing powder is less than 20%, it can improve crack resistance. When dosage of iron tailing powder is less than 20% and grinded iron tailing powder is less than 50%, specific strength and specific strength coefficient for 28 days are increased, and contribution rate of activity is greater than zero, which means that iron tailing powders benefit to strength.
