(This material can be mined and crushed for use as aggregate in concrete or fill materi- al, but is not cementitious.) Expanded blast-furnace slag: The light- weight cellular material obtained by con- trolled processing of molten blast-furnace slag with water, or water and other agents, such as steam or compressed air or both.

Utilization of Steel Slag in Concrete as Coarse Aggregate - Civil .

Slag aggregate sample was collected from the crushing plant of steel slag of a local steel manufacturing company. It was found that some slag aggregates were light in weight with a lot of voids and some were heavier with a little or no voids. Therefore, the slag aggregates were separated into three types, such as lightweight.
