#0183;#32;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.
The operation of the buildings is not included. For 1 kg EAF steel, the electric arc furnace was assumed to require kWh electricity (medium voltage, European mix, UCTE) and MJ natural gas. All other inputs as well as the emissions to air are given in Althaus et al. (2004).
An electric arc furnace (EAF) is a furnace that heats charged material by means of an electric arc. Industrial arc furnaces range in size from small units of approximately one ton capacity (used in foundries for producing cast iron products) up to about 400 ton units used for secondary steelmaking.

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.
Electric arc furnace slag Euroslag Electric arc furnace slag Electric arc furnace slag is produced during the manufacture of crude steel by the electric arc furnace (EAF) process. In this process steel scrap with additions of fluxes (, lime [stone] and/or dolomite) are heated to
Electric arc furnace oxidizing slag (EOS), in the fine aggregate form, can effectively be utilized as a construction material. However, its engineering properties vary with the manufacturing

#0183;#32;n this study the electric arc furnace slag was used as coarse nat ural aggregate substitute in concrete pav ing blocks production.
#0183;#32;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.
Electric arc furnace Wikipedia
Slag ing has become an important and critical practice for the modern electric arc furnace (EAF) since a good ing slag contributes considerable efficiency and other benefits to the process. The quality of the slag ing is an important factor in the EAF steelmaking process since it ensures that the heat from the liquid bath is not lost through the EAF walls.
The scrap is fed into the electric arc furnace and then, the graphite electrodes are lowered into place, starting the scrap fusion. The liquid EAFS, after chemical adjustments, is removed from the furnace and poured into cast carbon steel containers and transferred to an external area, where it
