Foundry wastes as a potential precursor in alkali activation technologyHorvat, Barbara (Avtor) Sešek Pavlin, Alenka (Avtor) Ducman, Vilma (Avtor) alkali activated materialsfoundry wastescompressive strengthupcyclingcircular ecnomyIn this study the amount of amorphous phase of elements useful in alkali activation of waste materials produced by the foundry industry was determined. Waste foundry sands, foundry flue gas and waste casting cores were alkali activated, and waste green ceramics and bottom ash were added to one of the foundry sand samples to shorten the time for producing measurable compressive strength from 1.5 years to 1 week.University Press, Faculty of Chemistry and Chemical Engineering20202024-03-01 08:26:19Neznano18306sl© University of Maribor, University Press Text / Besedilo © Authors & editors 2020
