Fly ash has been shown to be an effective replacement for portland cement in concrete mixtures. However many fly ash materials contain unburned carbon from the combustion process. Unburned carbon in fly ash adsorbs air entraining admixtures (AEAs) reducing their effectiveness in providing a specified air void system in concrete materials.
