Utilization of steel slag for Portland cement clinker production
The aim of the present research work is to investigate the possibility of adding steel slag, a byproduct 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 deg 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 (X-ray diffraction) analysis at 2 days, 7 days, 28 days 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.
