FA, or pulverised fuel ash, is a byproduct of coal-fired power plants and is used as a mineral additive in cement and concrete. Fig. 1 shows a typical layout of a coal-burning generating station. Pulverized coal is blown into the burning zone of the furnace, where its combustible constituents, mainly carbon, hydrogen, and oxygen, ignite at …

same time producing green and clean environment. Fly ash is of two types class F and C. Class F fly ash is produced by burning of harder, older anthracite and bituminous coals. This fly ash is pozzolanic in nature and contains less than 7% lime (CaO). However, class C fly ash is produced by burning of younger lignite sub-bituminous coal.
