KEYWORDS: concrete, beneficiation, LOI, air entrainment INTRODUCTION A practical problem with fly ash concrete is the tendency of residual carbon in ash to interfere with the air entrainment process. Porous carbon adsorbs the chemical surfactants (air entraining admixtures, or AEAs) used to generate and stabilize a micro- void system in concrete pastes, as shown by Helmuth (1987), Freeman et ...
