learn moreFly Ash Properties, Types, Mechanism and Uses
Fly ash is a heterogeneous byproduct material produced in the combustion process of coal used in power stations. It is a fine grey coloured powder having spherical glassy particles that rise with the flue gases. As fly ash contains pozzolanic materials components which reach with lime to form cementatious materials. Thus Fly ash is used in concrete, mines, landfills and dams.
