    Fly ash can be used as cement admixture. However, fly ash having high un-burned carbon content is not suitable for use as cement admixture. Beneficiation of fly ash is done in order to obtain carbon and fly ash fractions of high purity for their use as value-added products. Beneficiation is based on the difference in physical and surface properties of the carbon and ash.
