Slags, mixtures of mainly metal oxides and silicon dioxide, represent by-products or wastes generated by the ore smelting processes. There are several types of slags, but for construction applications as recycling possibilities, there are generally used slags generated by iron and steel making industry. The present study is focused on electric arc furnace slags (EAF), produced, and stored in the western part of Romania, Caransebeș city. The current slag deposit has been operating on this site since 1771, with the establishment of the furnaces to produce cast iron in Reșita. This paper presents a preliminary experimental study on the possibilities of using the Reșița SFS slags as a partial substitute for aggregate in cementitious materials for the construction industry. The opportunity and necessity of the proposed research direction cover several purposes: waste management implementation, environmental protection and natural resources saving, for the Circular Economy (CE) implementation in the Romanian industry. The initial results emphasise the concept's viability applied to the Reșita slag landfill, encouraging further exploration of this environmental engineering topic.
