FLY ASH

FLY ASH

CLASS F FLY ASH

Instead of volcanoes, today’s fly ash comes primarily from coal-fired electricity generating power plants. These power plants grind coal to powder fineness before it is burned.  Fly ash is a fine, glass powder recovered from the gases of burning coal during the production of electricity. These micron-sized earth elements consist primarily of silica, alumina and iron.

We supply Fly Ash that conforms to International Standard like ASTM C-618BSEN-450 & IS-3812. 

Application:

  • Manufacture of Portland Pozzolanic Cement
  • Performance improver in Ordinary Portland Cement (OPC)
  • Part replacement of OPC in cement concrete
  • Roller Compacted Concrete used for dam & pavement construction
  • Manufacture of ash bricks and other construction materials
  • Construction of road and embankments
