通过量热法、X射线衍射分析和Ca（OH）（2）含量测定，研究了钢铁加工副产物钢渣在复合胶凝材料水化过程中对水泥水化的影响。结果表明，钢渣和水泥通过改变水化环境，相互影响对方的水化。钢渣不与水泥的水化产物反应。水泥-钢渣复合胶凝材料在水化过程中的休眠期比水泥长。钢渣掺量越大，复合胶凝材料的休眠期越长。钢渣降低了水泥的早期水化速率。随着钢渣掺量的增加，这种现象更加明显。而钢渣对水泥后期的水化程度有促进作用，且随着钢渣掺量的增加和水化龄期的延长，其促进作用更加明显。
The influence of steel slag, a by-product from the processing of iron to steel, on the hydration of cement during the hydration process of complex binder was studied by calorimetry, X-ray diffraction analysis, and Ca(OH)(2) content determination. The results show that steel slag and cement affect each other's hydration by changing the hydration environment. Steel slag does not react with the hydration products of cement. The dormant period of cement-steel slag complex binder during the hydration is longer than that of cement. The more the adding amount of steel slag is, the longer the dormant period of complex binder will be. The steel slag decreases the early hydration rate of cement. This phenomenon is more obvious with the increment of steel slag addition. However, the steel slag can promote the hydration degree of cement at later ages and the promoting effect becomes more obvious with the increment of steel slag addition and the hydration ages.
