本研究工作的目的是探索在生产硅酸盐水泥熟料的生料中添加钢铁转化过程的副产品钢渣的可能性。制备了两个原料粉样品，一个用普通原料作为参考样品((PC)(参考文献))，另一个用10.5%的钢渣((PC)(S/S))。两种生料都在1450℃下烧结。化学和矿物学分析以及显微镜检查的结果表明，钢渣的使用没有影响如此生产的波特兰水泥熟料的矿物学特征。此外，通过测定熟料的可磨性、凝结时间、抗压强度和安定性对两种熟料进行了测试。分别于2、7、28、90d对水化产物进行X射线衍射分析。物理力学试验结果表明，钢渣的掺入不会对水泥的质量产生负面影响。(C)2007 Elsevier B.V.保留所有权利。
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. (c) 2007 Elsevier B.V. All rights reserved.
