Introduction of Flyash Bricks and Blocks

Fly ash brick (FAB) is a building material. its prepared by using coal ash.

Advantages of Fly Ash Bricks

1. Due to high strength, practically no breakage during transport & use.
2. Due to uniform size of bricks mortar required for joints & plaster reduces almost by 50%.
3. Due to lower water penetration seepage of water through bricks is considerably reduced.
4. Plaster of Paris / Gypsum Plaster can be directly applied on these bricks without a backing coat of plaster.
5. These bricks do not require soaking in water for 24 hours.
6. Only sprinkling of water before use is enough.
