Carbothermic reduction of Electric Arc Furnace Dust via thermogravimetry [PDF]

, 2018
Electric Arc Furnace Dust (EAFD) is a solid waste originated from electric steelmaking furnaces. Currently, according to some authors, there is an estimated generation of 15 to 25 kg of dust per ton of steel produced. The formation of the dust is related

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

, 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 ...
