The research in this communication examines the use Electric Arc Furnace (EAF)residues as aggregates in the construction industry. Here, we demonstrate the use of black slagas additional coarse, medium and fine hydraulic aggregate in the manufacture of Portlandcement. A complete physical and structural characterization of black steel slag is presentedand its properties are defined. Subsequently, we go on to examine concrete design criteria, byidentifying appropriate grading of the fraction to obtain a compact, resistant and durablematerial. The investigation is complemented by the study of the designed concrete, in freshand hardened states, as well as its durability when subjected to aggressive environments.Finally, it refers to certain achievements in this field and their applications in the buildingsector.37º <strong>IAHS</strong> <strong>World</strong> <strong>Congress</strong> On Housing Science 89
