Characteristics and applications of iron and steel slag

Steelmaking slag. Because of its hydraulic property and the large bearing capacity it can provide, steelmaking slag is used as a road base course material. With high particle density and hardness, this slag has superior wear resistance and for this reason is used as an aggregate for asphalt concrete.
