The aim of the present research work is to investigate the possibility of adding steel slag, a by-product of the conversion of iron to steel process, in the raw meal for the production of Portland cement clinker. Two samples of raw meals were prepared, one with ordinary raw materials, as a reference sample ((PC)(Ref)), and another with 10.5% steel slag ((PC)(S/S)). Both raw meals were sintered at 1450 degrees C. The results of chemical and mineralogical analyses as well as the microscopic examination showed that the use of the steel slag did not affect the mineralogical characteristics of the so produced Portland cement clinker. Furthermore, both clinkers were tested by determining the grindability, setting times, compressive strengths and soundness. The hydration products were examined by XRD analysis at 2, 7, 28 and 90 days. The results of the physico-mechanical tests showed that the addition of the steel slag did not negatively affect the quality of the produced cement.
本研究工作的目的是探讨在生产波特兰水泥熟料的生料中添加钢渣（钢铁转化过程中的一种副产品）的可能性。制备了两份生料样品，一份使用普通原料作为参考样品（(PC)(Ref)），另一份含有10.5%的钢渣（(PC)(S/S)）。两份生料均在1450摄氏度下烧结。化学和矿物学分析结果以及微观检查表明，钢渣的使用并未影响所生产的波特兰水泥熟料的矿物学特性。此外，通过测定粉磨性、凝结时间、抗压强度和安定性对两种熟料进行了测试。在2天、7天、28天和90天时通过XRD分析对水化产物进行了检查。物理力学测试结果表明，钢渣的添加并未对所生产水泥的质量产生负面影响。
