One of the most common is as a constituent of concrete and cement. Slag works very well as a loose aggregate and can be ground to produce a more even grain. It is also mixed with materials for making roadways, used as ballast on trains and large trucks, and is also applied as phosphate fertilizer.

What is the function of slag?
Slag floats on the surface of the molten metal, protecting it from oxidation by the atmosphere and keeping it clean. Slag forms a coarse aggregate used in certain concretes; it is used as a road material and ballast and as a source of available phosphate fertilizer.
Does slag break down?
Air-cooled blast furnace slag, even though is quite brittle and prone to breakdown under impact loading, has a hardness measured by the Mohs scale between 5 and 6 (similar to durable igneous rock).
Does slag have value?
Pelletized slag is generally used for lightweight aggregate but can be ground into material similar to GGBFS. Actual prices per ton ranged in 2019 from a few cents for some steel slags at a few locations to about $120 or more for some GGBFS.
How is slag formed?
Steel slag, a by-product of steel making, is produced during the separation of the molten steel from impurities in steel-making furnaces. The slag occurs as a molten liquid melt and is a complex solution of silicates and oxides that solidifies upon cooling.
