Advantages of Fly Ash Bricks

The raw materials for fly ash brick are: fly ash, sand/stone dust, lime, gypsum and cement. Fly ash bricks are lighter than clay bricks.

What are the advantages of using Fly Ash Bricks?

The main advantages of our bricks are listed below:
  • Saves Construction Cost: Due to uniform shape and size of the Fly Ash Brick, it saves labor in laying Bricks by about 15%. This translates into reduction in labor cost in laying each Brick, which is quite substantial.
  • High Compressive Strength: Our Bricks composition, ensure that we achieve compressive strengths of 60-75 kg/cm2 and above, which is 2-3 times the products in the market. Our fly ash bricks can be used in load bearing walls, with the guidance of Structural Engineers and Architects.
  • Environment Friendly: Our brick uses unfired Fly Ash technology hence the CO2 emissions in the manufacturing process are limited. Further use of our bricks helps in conservation of precious top-soil.
  • Excellent Thermal Insulation: The buildings using fly ash bricks are cool in summers and warm in winters. The high insulating property, with low embodied energy, of our products reduces the energy consumption of the buildings significantly by as much as 40-50%.
  • Excellent Sound Insulation: Fly ash bricks are sound absorbent and restrict sound transmission keeping the interiors very pleasant and quiet.
  • Fire Resistance: Fire resistance of fly ash bricks is very high as these bricks are composed of fly ash as its major constituents, which is the un-burnt residue of the coal fired in a thermal power plant.
  • Nil Efflorescence: Fly ash bricks resist salt and other sulphates attack, ensuring no efflorescence in the structure.

How do fly ash bricks compare with clay bricks?

Please refer to the comparison table below:
Sr.No. Properties Fly ash Bricks Conventional Clay Bricks
1 Basic Raw Material Fly ash Clay
2 Size & Quality Uniform ( Factory made) Uneven
3 Number of Joints in construction Less (uniform size) More (uneven size)
4 Mortar requirement Less More
5 Platering Less More
6 Direct Gypsum Plaster Possible Not Viable
7 Compressive strength More Less
