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 [.]
Fly ash is an extremely fine powder consisting of spherical particles less than 50 microns in size. Fly ash is one of the construction industry''s most commonly used pozzolans. Pozzolans are siliceous or siliceous/alumina materials possessing the ability to form cementitious compounds when mixed with lime (calcium hydroxide, or Ca(OH) 2) and water.
