Fly Ash Bricks

One of the greatest benefits of using fly ask bricks are that they have less thermal conductivity than clay bricks, which means that they reflect away heat and light . This translates to saving on electricity as they keep the rooms cool and brightly lit. These bricks also provide acceptable levels of sound insulation.

The fly ash bricks are higher on compressible strength as compared to the red bricks. Due to this the wastage on account of breaking is reduced drastically. They also provide better resistance to damage due to earthquakes and hence used in earthquake prone areas as well.

These bricks are low on water absorption (6-12%) as against 20-25% water absorption by clay bricks. This property helps in reducing the dampness in the walls- keeping the rooms dry and airy.


Other advantages of Fly Ash Bricks:

  • Uniform in shape and smooth in finish Lighter in weight
  • No plastering required for the building work
  • Dense composition
  • No Visible cracks
  • Less porous
  • Saves cost of mortar plastering
  • Aesthetically smart looking brickwork
  • Less wastage due to reduced cracking of plaster and high compressible strength
