Measuring concrete air-entraining admixture adsorption on coal ash using three-phase equilibrium and fluorescence-based methods

This manuscript presents two novel methods of evaluating the adsorption of air-entraining admixtures (AEAs) by coal ashes used in cementitious mixtures. A developed three-phase equilibrium (TPE) method measures fly ash adsorption capacity accounting for carbon adsorption, Ca2+ interactions with AEA,...
