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

When fly ash and bottom ash or both mixed together in any proportion with the large quantity of water to make it in slurry form and deposited in ponds wherein water gets drained away. The deposited ash is called as pond ash

What is Fly Ash

The properties of Fly Ash may vary widely both physically and chemically, depending upon the nature of the coal, the efficiency of the coal combustion process and the selection process

Therefore, its is important that when considering the use of Fly Ash to look no further than a company with in depth technical knowledge and support to manufacture and supply a high quality product, that company is
