摘　　要：针对两种主要的不锈钢渣(EAF渣和AOD渣)的水硬胶凝活性进行对比,并对其产生差异的机理进行探讨,指出EAF渣的胶凝性能明显高于AOD渣,可以替代部分水泥斟材料且符合42.5型和32.5型普通硅酸盐水泥强度指标。AOD不锈钢渣在配加少量稳定剂改性后,可显著提高其胶凝活性,达到与EAF渣胶凝性能相近水平。Difference and its mechanisms between various hydraulic cementitious properties of two main kinds of stainless steel slags,i. e. EAF slag and AOD slag,were compared and analyzed. It is found that,the cementitious property of EAF slag is better than that of AOD slag. Also EAF slag can be used to substitute for part of cement mortar admixture,and its stength can meet the criteria of portland cement.However,after adding few stablizers into AOD slag for modifying,its cementitious property can be obviously improved,which can be up to the level of EAF slag.
