Rebeca Martínez, in Recycled Concrete, 2023. 4.5 Blast furnace slag (BFS) Blast-furnace slag, BFS, is a by-product of iron when submitted to a blast furnace. It is mainly made up of silicate and aluminosilicate of melted calcium from the original iron ore combined with oxides from the limestone that is periodically removed from the blast …
Blast furnace slag is a nonmetallic byproduct of the manufacture of pig iron in a blast furnace. BFS consists primarily of silicates, aluminosilicates, and calcium-alumina-silicates. BFS forms when slagging agents (e.g., iron ore, coke ash, and limestone) are added to the iron ore to remove impurities.
