However CaO and Ca(OH) 2 are quite common in pellets anyways, as it is often added as a flux to the iron ore concentrate. Thus, in iron ore pelletization, class C and class F fly-ashes may both undergo pozzolanic reactions. Fly-ashes which do not meet ASTM C618 may still be useful as pellet binders, so long as they are pozzolanic.
