01-05-2007· BF (blast furnace) slag is generated in iron production and EAF (Electric Arc Furnace) slag is generated by steel production. The same is with Basic Oxygen Furnace (BOF) slag. Processing of EAF using traditional methods involves crushing and grinding.
THE USE OF ELECTRIC ARC FURNACE SLAG IN BITUMINOUS
The use of EAF slag fines has been rejected for warm mixes and water sensitivity in HMA was greatly worsened. Optimal moisture resistance appeared with slag as coarse aggregate and limestone as fines (Hesami et al., 2014; Oluwasola et al., 2015a, b). The expensive crushing procedures of EAF slag may also be noted that is on the whole
Electric Arc Furnace Slag as Coarse Recycled Aggregate for,
01-10-2015· EAF slag is a by-product of steel production, currently partially re-used in asphalt concrete [ 9 ]. However, huge quantities of this material are still landfilled. Different from other recycled aggregates, EAF slag has very good mechanical properties: it is a crushed product with black colour stone appearance and a rough surface texture.

The slag is mostly crushed, but it it's also partly agglomerated in lumps up to 2.5 meters in . diameter., EAF slag is waste material and is second highest to
Electric Arc Furnace Slag | ASA | Australasian (iron,
The slag is dark grey in colour and is characteristically harder than blast furnace slag (BFS). It has a density about 20 - 25% greater than basalt or BFS. It crushes to a cubical shape. EAFS in common with most steel slags, is

Steel Slag - an overview | ScienceDirect Topics
BBOF slag (BOFS) is produced in the steelmaking process by using the molten iron coming from the BF. In the second method, slags are generated in the scrap-based steel industry. The first stage of the scrap-based steel industry production generates EAF slag (EAFS) and a second stage is performed to refine the molten steel.

James G. Speight PhD, DSC, in Asphalt Materials Science and Technology, 2016 1.5.1.6 Slag. Slag aggregates are obtained by crushing of smelter slag or by special treatment of fire-liquid slag melt (molten slag aggregates). Currently there are many types of concrete that are developed and used in construction that include metallurgical slags both as a binding
