Fly ash bricks or FAB converts the industrial waste of fly ash into an effective building material. The manufacturing process uses less energy and the bricks come in uniform shapes and various sizes. As a building material it has gained importance in the construction sector in the recent past as it is light-weight, has higher strength (less breakage during transportation), offers high resistance to sound, has low water absorption and is a good thermal insulator. It also makes the job easier for electricians and plumbers as chiseling can be done with ease. FAB is used for load bearing walls and can result in making finer finishes with even surfaces. FABs are costlier than normal bricks by around 18 -25 per cent. However, on a larger scale, the cost of the project can be reduced as the dead load over the columns and beams are lesser, wastages minimal and they require less labour time.
