Project Description


Fly ash bricks are hi-tech well-improved quality bricks used for construction of brick masonry structures. They are used as replacement for normal clay bricks and has better properties than it.

Fly ash bricks are competitive in comparison to the conventional clay bricks and provide enormous indirect benefits. The utilization of fly ash bricks results in conservation of natural resources as well as protection of environment.



Advantages of Flyash Bricks:

  • 15% reduction in consumption of Bricks due to accurate dimensions

  • Heavy Compressive strength because of Dense Composition

  • 30% Cost reduction in plaster because of edged Finish

  • Less Porous hence low water absorption of only 5-8%

  • High Thermal Conductivity

  • Minimum Breakage i.e. higher cost savings

  • Time saving during Construction which means Fast Construction

  • Lower Noise Levels



Comparison between different brick types:

Cement Flyash Brick Clay Brick Lime Flyash Brick
Uniform in shape and smooth in finish Uneven shape as hand made Uniform in shape and smooth in finish
Exact 230 x 110 x 70 MM dimensions (15% reduction in number of bricks) Varying Dimensions (Mostly less in thickness) Varying Dimensions (Mostly less in thickness)
Dense Composition Lightly bonded Dense Composition
30% cost reduction in Plastering. Also Works Without Plaster. Plastering required Plastering required
