Types of Ash
Fly Ash
This kind of ash is extracted from flue gases through Electrostatic Precipitator in dry form. This ash is fine material & possesses good pozzolanic property.
Bottom Ash
This kind of ash is collected in the bottom of boiler furnace. It is comparatively coarse material and contains higher un-burnt carbon. It possesses no pozzolanic property.
Pond Ash
Fly ash & bottom ash or both mixed together in any proportion with the large quantity of water to make it in slurry form & deposited in ponds wherein water gets
