摘　　要：探讨钢渣粉和粉煤灰等量取代水泥后钢渣混凝土的力学属性变化特点和规律。实验对比表明 :与强度等级为 32 .5的纯水泥钢渣混凝土对比 ,掺入钢渣粉的砼强度略有降低 ,但能改善混凝土的和易性。掺入粉煤灰将增大混凝土的粘聚性和可塑性 ,改善混凝土的和易性 ,减小混凝土的膨胀性。The changing behavior of mechanics property and the law of slag steel concrete were studied as cement is replaced by steel slag powder and fly ash in this paper. By test analysis compared with strength degree 32.5 of cement, strength of steel slag concrete is slightly decreased,but its fluidity is improved. Chesion and plasticity of steel slag concrete is increased, its fluidity is improved and expansibility is decreased owing to addition of fly ash.
