Utilization of Carbonated BOF Slag as Partial Replacement of Aggregate in Cement Mortars
After direct mineral carbonation, a material rich in carbonates and with reduced quantities of free oxides is obtained. The aim of this work was to show that such materials can be used in the construction domain. Basic Oxygen Furnace (BOF) slag from the steelmaking process has been traditionally see...
