  • Beneficiation of Collie fly ash for synthesis of

    Although fly ash is suitable as a feedstock for synthesis of geopolymer its inherent heterogeneity limits development of a general formulation for producing geopolymer. Beneficiation of fly ash can be considered a method for alleviating this limitation leading to a more homogeneous geopolymer with improved properties.
