摘　　要：研究了钢渣微粉对混凝土路用性能和抗冻融循环能力的影响.结果表明:掺钢渣微粉可使混凝土路用性能和抗冻性能大幅提高,当钢渣微粉掺量为10%(质量分数)时,其抗折强度比普通基准混凝土提高约30%,脆度系数降低30%,耐磨性能提高13%以上.The effect of steel slag powder on road properties and freezing and thawing resistance of concrete was studied. The results show that the concrete with steel slag powder can enhance road properties and freezing and thawing resistance of concrete. The flexural strength of concrete with 10% steel slag powder added can be increased by about 30%, brittleness coefficient can be decreased by 30% and abrasion resistance can be enhanced by 13%.
