Segment 1

SARWAT NAQVI [IndiaUnheard, Chhattisgarh]
Fly ash is a by-product of thermal power. Let us find out how this fly ash is used to produce bricks that are used in the construction industry.
SARWAT NAQVI
What are the benefits of bricks made up of fly ash?
VIVEK CHAURASIA [Brick Factory Owner]
Fly ash is quite harmful to the environment if it is used in thermal factories. But, if fly ash is used as a by-product from a power plant, it could be mixed with other raw materials and made into bricks. In this way, it is eco-friendly and is put to good use.
SARWAT NAQVI
Can you tell us more about these fly ash bricks?
VIVEK CHAURASIA
Fly ash bricks are made mainly using three things: fly ash, gypsum, and lime. Sand and gravel are used as well. Fifty to sixty percent of this mixture consists of fly ash. All raw materials are mixed and pressurized in a machine to make bricks. This is a three day nurtured brick. You could toss this any which way, yet it wouldn't break. The most important process is the curing.
SARWAT NAQVI
How much curing is required?
VIVEK CHAURASIA
Twice a day, for a period of seven days. After seven days, these bricks are ready to be sold.
GOPAL [Building Contractor]
Ninety percent of people prefer this brick. Government engineers approve it. All the housing boards and other government construction in Raipur are using it. Its strength is suitable for heavy construction. And, it is clean too.
SARWAT NAQVI
So what is the benefit of these bricks in comparison with traditional red bricks?
ANJOR DAS [Building Contractor]
It is comparatively cheaper. They are bigger than red bricks. Fly ash bricks require less water to prepare.
VIVEK CHAURASIA
A majority of government projects, panchayat work, and housing board constructions would mandatorily have to use fly ash bricks.
SARWAT NAQVI
Chhattisgarh's environmental protection board has included fly ash bricks into third sector industry. There is a 35 percent subsidy on it. So in order to conserve the environment, this is a very good initiative. I hope these bricks are used more often in order to sustain a good environment.
