The burnt ash of the coal contains mostly silica, alumina, calcium, iron are the major chemical constituents. The chemistry of fly ash depends on the type of coal burnt in boiler furnace, temperature of furnace, degree of pulverization of coal, after this procedure we get fine fly-ash which is useful in many concrete applications.
