A direct alternative to primary aggregates, slag aggregates offer versatility and most importantly sustainable solutions to standard construction products. Steel aggregates have a high abrasion and crushing resistance for road applications: air cooled blast furnace products bond particularly well to cement and bitumous binders.

Synthetic aggregates may be either byproducts of an industrial process, in the case of blast-furnace slag, or products of processes developed to manufacture aggregates with special properties, as in the case of expanded clay, shale, or slate used for lightweight aggregates. Some lightweight aggregates such as pumice or scoria also occur naturally.
