Thermodynamic and kinetic investigation of carbothermic reduction of electric arc furnace dust

open access: yesMetalurgija, 2022
The thermodynamics and kinetics of electric arc furnace dust (EAFD) reduction were studied experimentally. The oxygen potential in the systems was determined by the electromotive force (EMF) method. Experimental equations for ΔG = f(T) were derived.

Utilization of bentonite in cementation of Cs-137-contaminated electric arc furnace dust

open access: yesNuclear Engineering and Technology
Cementation was employed to harden the Cs-137-contaminated electric arc furnace dust. The dust and cement were used as cementation binders. Bentonite was added to resist the Cs-137 leaching from the dust-cement-bentonite specimens.

Influence of electric arc furnace dust and lime kiln waste in Portland cement hydration [PDF]

open access: yes, 2020
Studies have indicated that the use of electric arc furnace dust (EAFD) results in a delay in the hydration time of Portland cement. Calcium-rich waste such as lime kiln waste (LKW) is one of the techniques used to offset this delay as it accounts for ...
