Fly ash - Wikipedia
Fly ash or flue ash, also known as pulverised fuel ash in the United Kingdom, is a coal combustion product that is composed of the particulates (fine particles of burned fuel) that are driven out of coal-fired boilers together with the flue gases.Ash that falls to the bottom of the boilers combustion chamber (commonly called a firebox) is called bottom ash.

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.
