#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.
#0183;#32;Electric arc furnace slag, crushed by the producer and supplied in three different sizes, fine (f), medium (m), coarse (c), was added as a partial substitution of the natural ones. The specific mass of EAFs, in the range kg/m 3 was compared to the corresponding values of natural aggregates in Table 1 .
Steel slag is a byproduct generated during the electric arc furnace (EAF) process in steel production, in which approximately 100150 kg of slag is produced per tonne of steel [1]. EAF uses zinc
#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 [26] .
When used as a constituent of raw meal for cement kiln, electric arc furnace (EAF) slag, being a source of noncarbonated lime, can contribute to a sustainable development in as much as both the kiln thermal requirement and CO2 generation are reduced. Ternary mixtures containing limestone, clay, and EAF slag (up to 35%), as a partial substitute
Electric Arc Furnace Slag (EAF Slag) As shown in Figure 1, slags are generally classified into two categories: Blast furnace (BF) slag and steelmaking (SM) arc furnace (EAF) slag, one of the SM slags, is produced by refining the process of recycled steel scrap in the electric arc furnace.
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.
slag produced in process of electric arc furnace steelmaking. Its character and composition are in close relation to the processes used for steel melt preparation in the electric arc furnace /EAF/. The use of two regime smelting with oxidation and reduction periods result in production of two types of slag.
Electric arc furnace slag (EAFS) is a coproduct of steel making process. The collected slags were broken down into small sizes. The tests conducted are aggregate crushing test, impact test, specific gravity test, water absorption test and angularity test.
#0183;#32;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. Particularly the reuse as coarse aggregate for concrete production has been shown to

Steel slag is a byproduct of the steelmaking and steel refining processes. This paper provides an overview of the different types of steel slag that are generated from basicoxygenfurnace (BOF) steelmaking, electricarcfurnace (EAF) steelmaking, and ladlefurnace steel refining processes. The mineralogical and morphological properties of BOF and electricarcfurnaceladle [EAF(L)] slag
Electric arc furnace carbon steel slag is a byproduct of the manufacture of steel by the electric arc furnace process (EAF). Production and Processing An EAF produces steel by the melting of recycled steel scrap, using heat generated by an arc, created by a large electric current.
Electric Arc Furnace Slag (EAFS) Brief Description . EAFS is a byproduct of the steelmaking process. EAFS solidifies in a similar manner to lava from a volcano. Its cooled structure is best described as a solid solution of oxides. Physical Description.
Electric Arc Furnace Slag (EAF Slag) As shown in Figure1, slags are generally classied into two categories: Blast furnace (BF) slag and steelmaking (SM) slag. Electric arc furnace (EAF) slag, one of the SM slags, is produced by rening the process of recycled steel scrap in the electric arc furnace. The main chemical characteristics of

Steel slag from a Basic Oxygen Furnace (BOF) and the Electric Arc Furnace (EAF). Ladle refining slag from the steel refining processes in the ladles. The blast furnace slag after granulation and grinding finds extensive use in cement and concrete. The steel slag, however, is yet to find a value added application except for its occasional usage
