A possible recycling method for high grade steels EAFD in polymer composites
Journal of Hazardous Materials, 2009This work evaluates the feasibility of incorporating electric arc furnace dust (EAFD), as filler in a polymer matrix, to obtain a moldable heavyweight sheet, useful for acoustic insulation in automotive industry. For this purpose EAFD from a steel factory that manufactures high quality steels, was characterized and different formulations of composites ...

The Effectiveness of Zn Leaching from EAFD Using Caustic Soda
Water, Air, & Soil Pollution, 2018Electric arc furnace dust (EAFD) is a toxic waste which is mainly rich in iron oxide, zinc, and lead. Hydrometallurgical extraction of zinc from Jordanian EAFD in alkaline medium was investigated; NaOH, NaHCO3, and Na2CO3 were used as leaching agents.

Dynamic creep analysis of Electric Arc Furnace Dust (EAFD) – Modified asphalt
Construction and Building Materials, 2017Abstract Electric Arc Furnace Dust (EAFD) is one of the by-products of steel making industry which has been classified as hazardous materials. This research aims at solving the problem of this hazardous waste by solidification/stabilization through mixing it with asphalt concrete mixtures.

Assessment of the potential for using EAFD in cement paste in Jordan
European Journal of Environmental and Civil Engineering, 2015This paper presents an experimental investigation on the effect of electrical arc furnace dust (EAFD) on normal consistency, setting time, soundness, dry bulk density and compressive strength of hardened cement pastes. EAFD dusts were used to partially replace cement at 0, 1, 3, 5, 10, 15 and 20% by weight.

Investigation of potential uses of electric-arc furnace dust (EAFD) in concrete
Cement and Concrete Research, 1997This paper presents the results of an investigation for the possible uses of electric-arc furnace dust (EAFD) by-product in concrete manufacturing. The effects of EAFD on the properties of fresh and hardened concrete are investigated. The results of standard tests on fresh concrete indicate that EAFD can be used as an effective set retarder.

Effect of electric arc furnace dust (EAFD) on properties of asphalt cement mixture
Resources, Conservation and Recycling, 2013Abstract Electric arc furnace dust (EAFD) is one of the by-products of steelmaking industry which has been classified as hazardous due to containing some heavy metals such as Zinc, Cobalt, Copper, Lead or Cadmium. This research aims at solving the problem of this hazardous waste by solidification/stabilization through mixing it with asphalt cement to

Key Engineering Materials, 2020
Indonesia coal ash is predicted to reach 10.8 million tons in the year 2020 but its utilization is still limited. In the last decade, coal ash has become a promising REY source candidate. To determine the potency of REY in Indonesia coal ash, information about element concentration and mineralogy of the ash is essential. In this study, coal ash samples

Possibility of carbon steel eafd solidification/stabilization in concrete
2013Steel scrap recycling is generally performed by direct smelting of scrap in an electric arc furnace, generating about 2% of dust per charge. Electric arc furnace dust (EAFD) is characterized as a hazardous material, due to its heavy metals content and a powder form.
