Composition Characteristics of Reconstructed Steel Slag with Electric Furnace Slag

Abstract:

Mineral compositions and granule morphology of reconstructed steel slag with electric furnace slag as an adjusting component were discussed. The vitreous content with hydrofluoric acid erosion and petrographic analysis were carried out. The results showed that the vitreous content of steel slag was lower than that of raw and first decreases and then increases as the calcination temperature increases; C₃S becomes hexagonal sheets or square columnar with the size of 40 to 60 microns and C₂S becomes spherical with size of 20 to 50 microns. Particle shape is more regular and the size is smaller than that of raw.
