Electric arc furnace (EAF) slag is a byproduct of steel production in electric arc furnaces. Several studies have tried to demonstrate its suitability in civil engineering application, such as in bituminous mixtures and cementbased materials, due to its good physical, chemical and mineralogical properties.
The functional analysis of electric scheme including an AC electric arc involves the use of techniques of modeling the electric arc that should reflect as closely as possible the behavior of the real electric arc. This can be done by means of general programs for nonlinear circuits, or programs that are specific for a more restricted domain.
Aug 15, 2015· The potential volumetric expansion of the electric arc furnace slag can be controlled and minimized during the production process in the factory. ° Among the particular characteristics of these slag concretes, the most important to be cited is a density of 5–20% higher than conventional concrete.
Electric arc furnace slag. Electric arc furnace slag is produced during the manufacture of crude steel by the electric arc furnace (EAF) this process steel scrap with additions of fluxes (, lime[stone] and/or dolomite) are heated to a liquid state by means of an electric current.
Blast furnace slag is used in blended cement. Although many studies have been conducted on the evaluation of the electric arc furnace slag to be use in concrete as aggregates replacing natural aggregates, no studies have been performed regarding the use of induction furnace slag in concrete as aggregates replacing natural aggregates.
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.

Today, iron and steel slag is used in many fields where its unique characteristics can be put to effective use. As a result of growing environmental awareness, iron and steel slag is highly regarded as a recycled material that can reduce impacts on the environment due .
Nowadays, the steelmaking industry has been transformed where plants, such as electric arc furnaces are used for more than 40% of global steel production in the world . This renewed industry has led to the appearance of a new byproduct: electric arc furnace oxidizing slag or black slag (EAFs).
utilization of steel slag in concrete. ASTM C33 6 gives specifications for the use of blast furnace slag as aggregates in concrete, while there is not such a standard for steel slag. In this order, the current study is focused on assessment of steel slag properties to be applied as aggregate in concrete.
Blast furnace slag is used in blended cement. Although many studies have been conducted on the evaluation of the electric arc furnace slag to be use in concrete as aggregates replacing natural aggregates, no studies have been performed regarding the use of induction furnace slag in concrete as aggregates replacing natural aggregates.
Electric arc furnace slag is a byproduct of the production of steel in an electric arc furnace. In electric arc furnaces the charge materials (scrap iron and steel) are loaded into the furnace and directly exposed to electric terminals. The current passing through the terminals creates an electric arc that melts the charge materials.
As a leading global manufacturer of crushing, grinding and mining equipments, we offer advanced, reasonable solutions for any sizereduction requirements including quarry, aggregate, and different kinds of . can we use electric arc furnace slag in concrete. cement electric eaf slag granulation plant. the electric steel making process ...
Electric Arc Furnace Slag in Concrete Journal of ... Dec 06, 2004 This stone 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.
Steel Steel Electricarc steelmaking: About onequarter of the world''s steel is produced by the electricarc method, which uses highcurrent electric arcs to melt steel scrap and convert it into liquid steel of a specified chemical composition and temperature. External arc heating permits better thermal control than does the basic oxygen process, in which heating is accomplished by the ...
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.
Therefore, in order to confirm the possibility of using electric arc furnace (EAF) oxidizing slag as a binder, a comparative assessment of the mechanical properties of concrete containing electric arc furnace oxidizing slag, steelmaking slag, and granulated blast furnace (GBF) slag was performed.
Electric Arc Furnace (EAF) : Charged material is heated to a liquid state by means of an electric current. The electricity has no electrochemical effect on the metal making it perfectly suited for melting scrap. Steel slag is processed as an aircooled material. The free metallics are magnetically separated and sized into construction ...
