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.

Hot iron bof andor scrap metal eaf are the primary metals to make steel in each process.Lime is injected to act as a fluxing agent.The lime combines with the silicates, aluminum oxides, magnesium oxides, manganese oxides and ferrites to form steel furnace slag, commonly called steel slag.Slag is poured from the furnace in a molten state.
The aod process is a secondary steel making process for the refinement and manufacture of different grades of stainless steels in a ladle furnace.This process produces a slag that is then further treated to prevent dusting of the aggregate.Both these slags are removed and tipped into pits where they are air cooled with the assistance of water.
Other uses include, skid resistant asphalt aggregate, rail ballast asphaltic concrete aggregate, soil conditioner, hard stand areas and unconfined construction fill.Electric arc furnace slag eaf or steel furnace slag produced when scrap metal and fluxes are oxidized by the use of an electric current.Molten slag is generally placed into.
Steel slag aggregate production process.If steel slag is used as an aggregate special attention should be paid to its mineralogical form due to its potentially expansive nature before utilisation as an aggregate it is recommended that steel slag be washed out additionally the use of slag containing more than 3 impurities and containing components of soft lime is not recommended.

The applications of steel slag powder and steel slag aggregate in ultra-high performance concrete uhpc were investigated by determining the fluidity, nonevaporable water content, and pore structure of paste and the compressive strength of concrete and by observing the morphologies of hardened paste and the concrete fracture surface.The results show that the fluidity of the paste containing.
2 the production of expanded blast furnace slag is no longer favored and is being replaced by the pelletizing procedure.Acbfs has been used as an aggregate in portland cement concrete, asphalt concrete, concrete, asphalt and road bases.Pelletized blast furnace slag has been used as lightweight aggregate and for cement manufacture.
In concrete, processed steel and blast furnace slag provide a sustainable alternative to primary aggregates in the production of lightweight or dense ready-mixed concrete.Blast furnace slag can also be used to make ground granulated blast-furnace slag ggbs which.
Steel slag aggregate ssa is a byproduct of the production of steel in an electric arc furnace.The high iron oxide content of the aggregate results in an aggregate that is very hard and very dense ssa is 20-30 heavier than naturally occurring aggregates such as basalt and granite.
