The main challenge of the steel industry for the next decade is the steel production transformation process, starting in Europe. The CO 2 intensive blast furnace/basic oxygen furnace (BOF) route will be substituted by a combination of Direct Reduced Iron (DRI), based on natural gas, later on "green" hydrogen, with an Electric Arc Furnace (EAF) or a …
It is also important to mention that the poor grindability of steel slag renders the production of fine powder from it both costly and energy-intensive [20], [21]. Therefore, the application of steel slag powder in cement concrete as a supplementary cementitious material is limited by its low reactivity, volume instability, and high abrasion ...
