Sažetak
The use of industrial by-products requires knowledge of the characteristics of the materials. This paper presents characterization data on slag generated in the melting of steel scrap by electric arc furnace (EAF). Characterization of electric arc furnace slag (EAFS), as one of the most significant types of non-hazardous metallurgical waste, was carried out through an examination of its physical and chemical properties with special emphasis on chemical and structural characteristics and potential use in road construction. Croatian EAF black steel slag, generated from carbon steel production process in CMC Sisak d.o.o., is the most interesting from the asphalt technology point of view, but in order to assess the suitability and reusing potential of EAFS in asphalt mixture production, it is necessary to know its chemical, radiochemical, physical, morphological, mineralogical, and textural characteristics, as well as how it interacts with individual segments of the environmental system. For this purpose, the study was carried out using several different analytical methods and this paper aims to explore the feasibility of utilizing steel slag as aggregates in asphalt mixtures. Optical Microscopy (OM), X-Ray Diffraction (XRD), Scanning Electron Microscopy (SEM) and Energy Dispersive Spectrometry (EDS) were employed to study the texture, morphology and composition of steel slag. Tests on the soundness of the slag for use as aggregate in road construction were carried out in accordance with European standards.
