Abstract: In 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.Keywords: alkali activated materials, foundry wastes, compressive strength, upcycling, circular ecnomyPublished in DiRROS: 01.03.2024; Views: 324; Downloads: 280 Link to fileThis document has many files!
