· 8. Class F Type Fly ash normally produced by burning anthracite or bituminous coal, usually has less than 5% CaO. Class F fly ash has pozzolanic properties only. In other word, the burning of harder, older anthracite and bituminous coal typically produces Class F fly ash. This fly ash is pozzolanic in nature, and contains less than 20% lime (CaO).

Fly Ash is a by-product material being generated by thermal power plants from combustion of Pulverised coal. High ash content is found to be in range of 30% to 50% in Indian coal [2] . The quantum of Fly Ash pr oduced depends on the quality of coal used and the operating conditions of
Fly ash is collected through the use of scrubber, or ESP systems (electrostatic precipitators). Dry ash removed by ESP systems is very abrasive due to its small particle size, physical hardness and the sharp edges of the particles. Once fly ash is removed, it is normally stored in some sort of hopper or silo.
