#0183;#32;This paper investigates the feasibility of using Black/Oxidizing Electric Arc Furnace slag (EAF) as coarse aggregate to produce High Performance Concrete (HPC). Various experimental mixes have been produced, fully replacing natural coarse aggregates with EAF slag, varying the cement dosages and the water/cement ratios, and they have been characterized through a mechanical and
In this paper the use of Electric Arc Furnace slag (EAF slag) for the production of HighPerformances Concrete (HPC) is explored, as a fully replacement of the natural gravel. Several mixtures were produced, varying the water/cement ratio, the cement and the admixture content, with the aim of reaching a strength class between C50/60 and C60/75, and an S4 consistency class, as defined in EN 2061.
Particularly the reuse as coarse aggregate for concrete production has been shown to be a promising valorisation, when physical and chemical sta bility is guaranteed. Additionally, EAF slags high mechanical strength makes it suitable for highperformance concrete production.
Electric arc furnace (EAF) slags come from the use of electric furnace technology, where scrap steel is the main feed and either oxidizing or reducing processes are realized (Lee et al., 2019).
Electric arc furnace granulated slag for sustainable concrete. The electric arc furnace slag generally used as a substitute for natural aggregate in concrete is sharpcornered with a honeycombed surface texture. This characteristic can be useful to develop very strong interlocking properties [26] .

Electric Arc Furnace Slag Electric Arc Furnace slag (EAF slag) can substitute natural aggregates in asphalt and concrete is a by#173;product that has been used for decades in Europe, USA and Japan in construction due to its unique physical and mechanical Qatar (EBMQ) specializes in optimizing the use of EAF slag offering complete []
Electric arc furnace oxidizing slag (EAFS) is a byproduct of the steelmaking industry, generated after the melting and the preliminary acid refining of liquid steel. It is a stony material that is easy to crush for use as aggregate in concrete mixes.
#0183;#32;Steel melting through electric arc furnace route is gaining popularity due to its many advantages, but generates a new waste, electric arc furnace slag, which is getting accumulated and land/mine filling and road construction are the only utilization. This slag has been tried to be value added and utilized to develop vitreous ceramic tiles.
This paper describes the work carried out in laboratory to produce concrete with good properties using oxidizing electric arc furnace (EAF) slag as fine and coarse aggregate. To do this, the slag obtained in the steelmaking process must be crushed and stabilized. First, a suitable mortar must be made and tested.
#0183;#32;In this context, several slag types derived from steel production may be listed: blast furnace slag (BFS), electric arcfurnace oxidizing slag (EAF), ladlefurnace basic slag (LFS), etc. According to the World Steel Association, world crude steel production has increased from 849 Mt in 2000 [1] to 1690 Mt for the year 2018 [2] .
The use of oxidizing slag from electricarc furnaces as an aggregate is a sustainable option in the manufacture of concrete, the performance of which is similar to an ordinary aggregate concrete.

Electric arc furnace (EAF) slag, a byproduct of steelmaking recovered after the oxidizing process, is useful when employed as aggregate in hydraulic concrete and bituminous mixtures.
For sustainable development in the construction industry, blast furnace slag has been used as a substitute for cement in concrete. In contrast, steelmaking slag, the second largest byproduct in the steel industry, is mostly used as a filler material in embankment construction. This is because steelmaking slag has relatively low hydraulicity and a problem with volumetric expansion.

The main byproducts of the steel industry, blast furnace (BF) slag and steelmaking (SM) slag, can partially replace cement in concrete because of its potential hydraulicity [1,2,4,5,6,7,8,9].According to previous studies, about 70% of the total production of BF slag has been used as a replacement for Portland cement due to its numerous advantages,, an increase in longterm strength and
