Blast Furnace Slag Cement (Application, Pros & Cons)

    Blast Furnace Slag (BFS) cement is the combination of Ordinary Portland Cement (OPC) and fine Granulated Blast Furnace Slag (GBFS) gained as a byproduct in the steel making manufacturer with below 70% to that of cement. Ground Granulated Blast Furnace Slag (GGBFS) is a fine glassy granule which encompasses cementitious possessions.

    While GGBF slag particles may be similar in size to cement particles, they have a specific gravity of about 2.85 to 2.9, compared with portland cement (around 3.15). If the producer replaces GGBF slag pound for pound for cement, the mix would overyield. Many adjust the yield by reducing the fine aggregate (sand).
