Jan 25, 2018· Figure 1. Slag aggregate was used to build the Roman Appian Way over 2000 years ago. Source: National Slag Association Every day you probably use a steel industry byproduct, slag, without realizing it. Slag is a common construction material in the building of roadways, bridges and buildings.
Slag is a product of the steel making process. Once scorned as a useless byproduct, it is now accepted and, often, preferred and specified as it is known to be a valuable material with many and varied uses.
plants often use a mix of DRI and recycled steel feeds. On average the production of one tonne of steel results in 200 kg (EAF) to 400 kg (BF/BOF) of coproducts. These include slags, dusts, sludges and other materials. Ironmaking and steelmaking slags More than 400 million tonnes of iron and steel slag is produced each year.

Recycling benefits of steel slag: Steel slag is a kind of solid waste that is produced in the process of steel production, it mainly consists of blast furnace slag, steel slag, iron bearing dust (including iron oxide scale, dust, blast furnace dust, etc), coal dust, gypsum, rejected refractory, etc.
The steel slag produced during the primary stage of steel production is referred to as furnace slag or tap slag. This is the major source of steel slag aggregate. After being tapped from the furnace, the molten steel is transferred in a ladle for further refining to remove additional impurities still contained within the steel.
