Gray Fly Ash Bricks (Fab)

We are making, exporting, distributing and supplying Fly Ash Bricks (FAB) in Mumbai, Maharashtra, India. Fly ash brick (FAB) is a building material, specifically masonry units, containing class C or class F fly ash and water. Compressed at 28 MPa (272 atm) and cured for 24 hours in a 66 A C steam bath, then toughened with an air entrainment agent, the bricks last for more than 100 freeze-thaw cycles. Owing to the high concentration of calcium oxide in class C fly ash, the brick is described as "self-cementing". The manufacturing method saves energy, reduces mercury pollution, and costs 20% less than traditional clay brick manufacturing.

Ever since FaL-G (Fly ash-Lime-Gypsum) process is introduced in 1991, fly ash brick activity has been revolutionised in India. FaL-G technology () developed and patented by Dr Bhanumathidas and Kalidas has simplified the process by adding gypsum to fly ash+lime/cement, converting the calcium aluminates into calcium alumino-sulphates resulting in to achieve high early strengths.Thus FaL-G brick does not need any pressure and gets cured at ambient temperature of 20-40 A A C. By avoiding both press and heating chamber, FaL-G process has brought down the multi-million plant cost to a few lakhs, within the reach of micro units
