Fly Ash
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.
Fly ash explained
Fly ash material solidifies while suspended in the exhaust gases and is collected by electrostatic precipitators or filter bags. Since the particles solidify rapidly while suspended in the exhaust gases, fly ash particles are generally spherical in shape and range in size from µm to 300 µm. The major consequence of the rapid cooling is that few minerals have time to crystallize, and that ...
