Slag is also mixed with materials for making roadways, used as ballast on trains and large trucks, and is also applied as phosphate fertilizer. When used as fertilizer, the slag is ground very fine before being spread, and it slowly time releases nutrients because it takes a long time to break down...

Slag cement, often called ground granulated blast-furnace slag (GGBFS), is one of the most consistent cementitious materials used in concrete. Slag cement is actually a byproduct of iron production. When the iron is processed using a blast furnace, slag and iron both collect at the bottom of the furnace.

Slag cement is most widely used in concrete, either as a separate cementitious component or as part of a blended cement. It works synergistically with portland cement to increase strength, reduce permeability, improve resistance to chemical attack and inhibit rebar corrosion.
