Wasteless Joint Processing of Ladle Furnace and Electric Arc Furnace Slags
Steel in Translation, 2021The urgent problem regarding the depletion of mineral resources in ferrous metallurgy can be efficiently solved by a complex reuse of man-caused waste products. Such wastes are mostly presented by electric arc furnace (EAF) slag and ladle furnace (LF) slag. These two kinds of slag are not completely utilized.

Electric Arc Furnace Slag in Concrete
Journal of Materials in Civil Engineering, 2004This 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.

New Geopolymers Based on Electric Arc Furnace Slag
Advances in Science and Technology, 2010Electric arc furnace slag (EAF-S), coming from a steel productive plant in Italy, has been used as new source for geopolymers synthesis. The slag has been geopolymerized alone and with different content of metakaolin (MK) with the aim to investigate if EAF-S content plays a role in geopolymerization process.

Phosphorus removal by electric arc furnace steel slag and serpentinite
Water Research, 2006Electric arc furnace (EAF) steel slag and serpentinite were tested in columns either alone or mixed with limestone to determine their capacity to remove phosphorus (P) from a solution containing initially 20mg P/L (for 114 days) than 400mg P/L (for 21 days). EAF steel slag was nearly 100% efficient due to specific P adsorption onto metal hydroxides and

Electric Arc Furnace Slag Concrete
2016The aim of this section is to comprehensively investigate the possibility of substituting natural aggregates with Black/Oxidizing Electric Arc Furnace (EAF) slag, at high replacement ratios, to produce structural concrete. The properties of the slag are described in detail, in terms of chemical composition, mineralogy, microstructure and physical ...

Valorization of Electrical Arc Furnace Oxidizing Slag
2014Valorization of the electrical arc furnace oxidizing slag by coke was carried out by the reduction of iron oxide in the slag. Since the reduction of iron oxide by solid carbon is an endothermic reaction, supply of heat energy is required. In addition, slag has a low thermal conductivity; traditional fuel injection is not suitable for this reaction ...

Construction and Building Materials, 2019
Abstract Basic oxygen furnace (BOF) slag mud and electric arc furnace (EAF) slag were characterized by TG-DSC, XRD, FTIR, 27Al MAS-NMR and ICP-MS techniques to correlate structural characteristics with cementitious behavior. BOF slag mud is a by-product discharged after the wet milling and magnetic separation of basic oxygen furnace steel slag.

Properties of Blast Furnace Slag Cement Modified with Electric Arc Furnace Slag
Journal of the Korean Ceramic Society, 2006Properties of slag cement that contained 50 wt% of blast furnace slag were studied when replaced blast furnace slag powder with electric arc furnace slag powder. Electric arc furnace slag was aged for about 2 months in the air by being crushed to be 1-3mm in size.

The CO2 sequestration by supercritical carbonation of electric arc furnace slag
Journal of CO2 Utilization, 2021Abstract The current study puts the emphasis on developing a supercritical carbonation process of electric arc furnace slag for the CO2 sequestration. In this process, the feed is mixed with water and processed with supercritical CO2 at 40−80 °C and 80–120 bar for 48 h.
