Effects of the Chemical Composition of Synthetic Slags Compared to an Average Blast Furnace Slag

Abstract:To study the effect of the main oxides and the minor components in slags on their reactivity as SCM, various glasses were synthesized to stepwise imitate a commercial slag of average chemical composition. First, a glass was produced from the main oxides CaO, Al2O3 and SiO2. In a second step, the minor components MgO, Fe2O3, Na2O and K2O were added separately to the main oxide mix. A selection of two synthetic glasses was tested for their compressive strength contribution (up to 90 days) by substituting 20 wt.%… Show more
