Fly Ash Brick
Manufacturers Association

The association derives its purpose from the aim of constructive "Utilization" rather than "Disposal" only of Fly Ash and we believe in coming together to achieve better results for a "Green India Clean India".

Comparative Chart of Fly Ash Bricks and Red Clay Bricks
S.NO. Properties FLY ASH BRICKS BIS-12894 (2002) 230mmx110mmx70mm RED CLAY BRICKS
1. Compressive Strength As per BIS-3495 Part 70-120 kg/sqcm. 30-80 kg/sqcm.
2. Water absorption As per BIS: 3495 Part 2 12-16% : <20% max. codal specification is 20% 10-35%
3. Choice of Density 1200-1700 kg/cumtr. Light Weight 1800 kg/cumtr.
4. Carbon Dioxide (CO 2) Emission Zero CO 2 Emission. 1 Ton fly ash used saves appx. 1Ton CO 2 emission to the environment One sq. ft. of carpet area will emit 17.6 kg of CO2
5. Fuel Consumption No Coal required One sq. ft. of carpet area with clay bricks will consume 8 kg of coal.
6. Fertile soil consumption Zero Soil Consumption instead Fly Ash Consumption up to 80% One sq. ft. of carpet area with clay brick walling will consume 25.5 kg of fertile top soil.
7. Efflorescence As per BIS :3495 Part 3 Zero- Resulting in Brick getting stronger with passage of time Usually after 25-30 days of building masonary- gets weaker & weaker
8. Wastage/Breakage 1-2% 10-15%
9. Mortar Joint Thickness & Saving 08-10 mm i.e. up to 20% less Mortar required due to uniform shape & size 15-18 mm moreover Non uniform shape & size leads to considerable wastage of Mortar
10. Plaster Thickness & Saving 10-12 mm i.e. up to 50% due to uniform wall surface- Direct Gypsum Plaster can be applied as per specifications 15-20 mm minimum but Irregular & uneven wall surface require thicker & non-durable plaster
11. Thermal Insulation/Energy saving 15%-30% better Zero
12. Volume & Carpet Area Saving 100 Sqft. 9" Wall requires- 925 Bricks due to even and uniform size of bricks. 100 Sqft. 9" Wall requires-1100 Bricks due to irregular non uniform brick size
13. Cost saving 25-30% less cost of construction Wastage of materials leading to cost escalation & expensive construction.
