Fly ash bricks have high compressive strength and low water absorption (6-12%). They are light in weight and have high strength to weight ratio. They are less porous and have a thermal conductivity of 0.90-1.05 W/m2°C. Bricks have uniform pleasing colour like cement. They are uniform in shape and smooth in finish. No plastering is required. They also have dense composition.

This technology is economical and environment friendly. There is no emission of greenhouse gases during production. Required operational area is smaller than any other brick producing unit.

The fly ash bricks have high compressive strength. The strength of the bricks can be engineered by varying compositions of fly ash, additives and filler materials. The bricks have a metallic ring to it. The bricks have uniform pleasing colour like cement. They have low water absorption.

Fly ash collected from electrostatic precipitators (ESP) or silos of thermal power plants in dry state can be used for brick production.

Yes, this technology is economically feasible. The machines cost can be upto INR 12 lakhs (24,000 USD). The working capital is approximately INR 5 lakhs (10,000 USD). It’s payback period is 2 years.

No, skilled manpower is not required to operate a Building material unit. Upto 10 people are required to run a Building material production unit. They can be easily trained on the site itself.
