Investigation of potential uses of electric-arc furnace dust (EAFD) in concrete [PDF]

open access: yesCement and Concrete Research, 1997
This 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, 2013
Abstract 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

Effects of electric arc furnace dust (EAFD) addition on setting and strength evolutions of cement pastes and mortars [PDF]

open access: yesEuropean Journal of Environmental and Civil Engineering, 2017
AbstractThe purpose of this work is to study the effects of including high dosage of electric arc furnace dust (EAFD) on both setting behaviour of cement pastes, and on strength evolution of eco-friendly mortars. Particularly, in this research, dust was taken in as-received conditions from the collection system of a carbon steelmaking factory.

Study of electric-arc furnace dust (EAFD) in fly ash and rice husk ash-based geopolymers

Advanced Powder Technology, 2017
Abstract Electric-arc furnace dust (EAFD) is an industrial waste produced by the volatilization of metals during scrap melting in electric arc furnaces. This waste is classified as Class I – hazardous, because lead and cadmium concentrations are above the limits set in the leaching test.

Oxide zinc addition in cement paste aiming electric arc furnace dust (EAFD) recycling

Construction and Building Materials, 2017
Abstract Large amounts of electric arc furnace dust (EAFD) are generated in steel production, highlighting the need for recycling alternatives like the use of EAFD in production of building materials. However, EAFD delays hydration reactions of concrete.
