Characterization and Cementitious Properties of BOF Slag

Different techniques were used to characterise BOF slag. The main mineral phases of steel slag are dicalcium silicate C2S , trecalcium silicate C3S and dicalcium ferrite C2F, and C4AF. Some minor phases as ferrite oxides (FeO,Fe2O3) were also identified. The cementitious test indicated that strength...

Description
Summary:Different techniques were used to characterise BOF slag. The main mineral phases of steel slag are dicalcium silicate C2S , trecalcium silicate C3S and dicalcium ferrite C2F, and C4AF. Some minor phases as ferrite oxides (FeO,Fe2O3) were also identified. The cementitious test indicated that strength of mortar decreased with the increasing of steel slag replacement, and the sample with finer steel slag tends to gain higher strength. Steel slag exhibited significant adverse effect on the early strength, but benefited at late ages.
