Market Demand

• The country consumes about  180 billion tones bricks, exhausting approximately 340 billion tones of clay every year and about 5000 acres of top soil land is made unfertile for a long  period. The Government is seriously concerned over soil erosion for production of massive  quantities of bricks, in the background of enormous housing needs.
•  The excellent engineering  property and durability of fly ash brick enlarges its scope for application in building  construction and development of infrastructure, construction of pavements, dams, tanks, under  water works, canal lining and irrigation work tc.
• Enormous quantities of fly ash are available in and around thermal power stations in all the states. The demand of bricks could be met by establishing small units near thermal power stations and  to meet the local demand with less transportation costs.

The important compositions of fly ash bricks are as follows:

• Fly Ash
• Cement
• Sand
• Water

Future Scope

• The  use  of  100%  fly  ash  can  be  more  economical and  may  play  an  important  role  in  light  weight structure so, it may be investigated.
• Further study can be done on fly ash + cement and compared with fly ash -clay bricks.
• The  similar  work  may  be  done  by  taking  different proportions of ingredients

The highlights of the notification was-

• Use of fly ash, bottom ash or pond ash in the manufacture of bricks and other construction activities :
  • Within a radius of 100 km from coal or lignite based thermal power plants, no person shall manufacture clay bricks, tiles or blocks (for use in construction activities) without mixing at least 25% of ash with soil on weight basis.
  • The authority for ensuring the use of specified quantity of ash shall be the concerned Regional Officer of the State Pollution Control Board. In case of non-compliance, the authority (in addition to cancellation of consent order issued to establish the brick kiln) shall move the district administration for cancellation of the mining lease. To enable the authority to verify the actual use of ash, the thermal power plant shall maintain monthly records of ash made available to each brick kiln.

Availability of fly ash for brick making

• Every thermal power plant shall make available ash, for at least ten years without any payment or any other consideration for the purpose of manufacturing ash-based products.
• Central and State Government Agencies, State Electricity Boards, NTPC and the management of the thermal power plants shall facilitate in making available land, electricity and water for manufacturing activities and also provide access to the ash lifting area. This will promote and encourage setting up of ash-based production units proximate to the area where ash is generated by the power plant.

Specifications for use of ash based products

• Every construction agency engaged in the construction of buildings within a radius of 100 km from thermal power plants shall use fly ash bricks in construction projects. It shall be the responsibility of the construction agencies (either undertaking the construction or approving the design or both) to ensure compliance.
