Verification of Durability Properties of Alkali-Activated Materials Based on Blast Furnace Slag with Fly Ash

Abstract:

The paper deals with the possibility of using fly ash, including fly ash after denitrification by SNCR method, from the Třebovice power plant as an admixture to mixtures based on alkali-activated blast furnace slag in order to improve selected physical, mechanical and durability properties.
