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. |
