1·The effect of steel slag powder on road properties and freezing and thawing resistance of concrete was studied.
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。
2·Usually steel slag is used as metallurgical materials, cement, roadbed materials, construction materials and phosphate fertilizer.
普通钢渣经处理可作冶金原料、水泥、路基材料等建筑用料和磷肥。
3·By test analysis compared with strength degree 32.5 of cement, strength of steel slag concrete is slightly decreased, but its fluidity is improved.
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。
4·Steel slag and paper industrial waste sludge were carbonated to produce concrete aggregate.
碳酸化养护钢渣和造纸污泥制备混凝土集料。
5·Steel slag is a byproduct of steel industry.
钢渣是钢铁工业的副产品。
