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.
The use of steel slag as an aggregate is considered a standard practice in many jurisdictions, with applications that include its use in granular base, embankments, engineered fill, highway shoulders, and hot mix asphalt pavement.
Moreover, Is steel slag safe?
When SSRS compares with ground granulated blast furnace slag (GGBFS) from iron making, steel slag contains toxic ingredients such as nickel, cadmium, chromium and strontium. These compounds could be harmful not only for environment but also for human health [9,10].
Secondly, What is slag rock used for?
Due to its positive technical characteristics, LD slag is used all over the world in road and railway construction and for engineering. The most common use is as an aggregate in the manufacture of asphalt. It is also successfully used as an aggregate for concrete.
Simply so, What is steel slag made of?
The primary components of iron and steel slag are limestone (CaO) and silica (SiO2). Other components of blast furnace slag include alumina (Alsub>2O3) and magnesium oxide (MgO), as well as a small amount of sulfur (S), while steelmaking slag contains iron oxide (FeO) and magnesium oxide (MgO).
Is steel slag used in agriculture?
Slags are rich in Silicon (Si) and other fertilizer components, such as Ca, Fe, Mn, and P2,3,4. These beneficial properties of the slag can be exploited to improve agricultural productivity. The liming nature of slag increases soil pH and helps in nutrient mobilization and improves plant productivity1.

What is iron slag made of?
Iron and steel slag, also known as ferrous slag, is produced by adding limestone (or dolomite), lime and silica sand to blast furnaces and steel furnaces to strip impurities from iron ore, scrap and other ferrous feed materials and to lower the heat requirements of the iron- and steelmaking processes.
What is slag in steel?
Steel slag, a by-product of steel making, is produced during the separation of the molten steel from impurities in steel-making furnaces. The slag occurs as a molten liquid melt and is a complex solution of silicates and oxides that solidifies upon cooling. The open hearth furnace process is no longer used.
