摘   要：研究了5种不同激发剂（单掺、复掺）对钢渣活性及水泥强度的影响。通过水泥细度负压筛、压力试验机、X射线衍射仪、扫描电子显微镜等测试和检测方法揭示了钢渣的宏观性能和微观结构的内在联系。结果表明，掺加了激发剂和糖蜜的钢渣粉磨效率更高。单组分激发剂中，掺入硫酸钠的钢渣试样早期强度提升明显；偏铝酸钠的早期强度很低而后期强度高。在复合激发剂中，硫酸钠与铝酸钠复掺的效果最好，28d强度较纯钢渣试样提高了42%，活性指数K28达到88.2%，其次是硫酸钠与硅酸钠复掺，28d钢渣强度较纯钢渣试样提升了35%，活性指数K28达到82.5%。

Abstract: The effects of 5 kinds of activators on the activity and strength of cenment with steel slag were studied. By means of cement fineness, negative pressure screen, pressure test machine, XRD and SEM, the macroscopic and microscopic internal relations of steel slag are revealed. The results show that the grinding efficiency of steel slag added with activator and molasses is higher. When the activators is singly added, the early strength of steel slag samples with sodium sulfate significantly enhanced, and early strength of steel slag samples with sodium aluminate is very low, but the later strength is high. When the activators is compound added, the compound effect of sodium sulfate and sodium aluminate admixture is the best, compared with the pure steel slag sample, its 28d strength increases 42%, and the K28 activity index reaches 88.2%, the followed compound effect is sodium sulfate and sodium silicate admixture, compared with the pure steel slag samples, the 28d strength increases 35%, and the K28 activity index reaches 82.5%.
