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.
GGBFS is gained as a derivative in the removal of iron from its ore. The procedure of removal of iron is the blast furnace. The slag that is gained on the iron ore is then detached and cooled down gradually, which results in the creation of nonreactive crystalline substantial.Further this slag is grounded finely as that of cement and mixed in the proportion as per the requirement. Different percentage of GGBFS is added for different type of construction.
