 Information Profile @ a Glance  
  • Rice yields can be improved over and above yields obtained with regular use of fertilizer by addition of rice husk ash.

  •  Every 1000 kgs of paddy milled , about 220 kgs of husk is produced  and when this husk is burnt in the boilers , about 55 kgs  of RHA is generated

  • This husk contains about 75 % organic volatile matter  and the balance 25 % of the weight of this husk  is converted into ash during the firing process , is  known as rice husk ash ( RHA ). 

  • Rice hull can also serve as a moisture retention helper or as a weed growth inhibitor in a soil. 

  • RHA acts as a very good Insulator and is used for the insulation of molten metal in tundish and ladle in slab caster.

  • Rice husk contains silica in hydrated amorphous form and cellulose which yields carbon when thermally decomposed.

  • Rice husks have been used in manufacturing block employed in civil construction as panels and was used by the rice industry itself as a source of energy for boilers.

  • RHA is a good super-pozzolans.

  • Rice husks may be used as energy sources in a number of forms.

  • India is a major rice producing country , and the husk generated during milling is mostly used as a fuel in the boilers for processing paddy.

  • RHA contains around 85 % - 90 %  amorphous silica.

  • There is a growing demand for fine amorphous silica in the production of special cement and concrete mixes high performance concrete , high strength, low permeability concrete, for use in bridges, marine environments , nuclear power plants

  • Largest and most commercially viable markets appear to be in the concrete and steel industry.
