This nonmetallic slag material can either be crushed and screened for aggregate use (steel slag aggregates), or sintered and recycled as flux material in the iron and steel furnaces. Steel slag aggregates generally exhibit a propensity to expand.
Slag is sometimes erroneously classified as industrial waste. In fact, this product can be recycled into valuable, versatile construction materials for green use. We utilize slag, a product of steelmaking, in versatile construction material for environmentally beneficial use.
In the aggregates industry, these rocks are classified as crushed stone, sand, gravel and slag. We use aggregates every day. Streets, bridges, roads and sidewalks are made of concrete or asphalt which is mostly made up of aggregates combined with a binder that acts like glue.
The steel slag produced during the primary stage of steel production is referred to as furnace slag or tap slag, Steel Slag Aggregates Use in Hot Mix Asphalt . Get More Info Basics of slag production - Article on the slag industry,
Blast furnace slag is allowed to slowly cool by ambient air, is processed through a screening and crushing plant and is processed into many sizes for use primarily as a construction aggregate. Common uses are as aggregates in ready-mix concrete, precast concrete, hot mix asphalt aggregate, septic drain fields and pipe backfill.

Granulated blast furnace slag has been used as a raw material for cement production and as an aggregate and insulating material. and granulated slag have also been used as sand blasting shot materials.
Slag, as the term will be used here, is any siliceous melt that arises in significant quantity from the various processes used in the production of iron and steel, and more particularly the solid materials that forms when such melts cool.
The use of slag aggregates from iron and steel production in construction dates back to the Romans who used crushed slag from the crude iron production of that time to build their roads. Nowadays, slag is still used to build roads.
Many researchers have investigated the use of copper slag in the production of cement, mortar, and concrete as mixed with lime stone powder, dust, cement replacement, use as partial replacement of coarse, and fine aggregates.
Ground-granulated blast-furnace slag (GGBS or GGBFS) is obtained by quenching molten iron slag (a by-product of iron and steel-making) from a blast furnace in water or steam, to produce a glassy, granular product that is then dried and ground into a fine powder.
