Fly Ash


Fly-ash is a burnt and powdery derivative of inorganic mineral matter that generates during the combustion of pulverized coal in the thermal power plant. 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.

Benefits and Use of Fly-Ash:

  • Manufacturing of fly-ash bricks
  • Manufacturing of fly-ash based AAC blocks
  • Manufacturing of asbestos sheets
  • Manufacturing of asbestos pressure pipes
