Recycling Coal Plant Residue to make Bricks

For the past few decades, we are using fly ash bricks instead of clay bricks because of light weight, high strength, uniformity and less consumption of mortar plastering. These are the common understanding many of you known about fly ash bricks. Let's go deeply about in what way fly ash brick is better than conventional clay bricks.

Clay bricks vs. Fly ash Bricks

Clay bricks are manufactured by using the fertile top soil and are made in sheds. Continuing use of clay bricks will lead to extensive loss of fertile top soil and no fertile land for future agriculture. Deforestation also occurs in search of soil source for clay brick manufacturing. Unlike clay bricks, fly ash bricks are made through a mechanized manufacturing process. So, weather variation does not affect the brick manufacturing process.

Moreover clay bricks have no quality testing facilities, so its quality can't be guessed. Whereas, fly ash bricks are manufactured using pre-programmed hydraulic machines. Bricks from these machines are tested for its quality and durability.

Why Fly ash Bricks?

Fly-ash, an unwanted residue obtained from coal-fired power plants. By adding cement, lime, water, gypsum with fly ash to make bricks. These bricks are lighter and stronger, and they reduce the plastering cost by 30 percent.

Fly-ash bricks are increasingly gaining acceptance in construction because of cost effective, durable, fire and moisture resistant and most importantly environment friendly. With the restriction on the use of clay in manufacturing of bricks, Fly Ash Brick is a best substitute for it.

With the excessive amount of fly ash released every year from coal-fired power plants, luckily we got an option to turn this ash residue into useful construction material. Yes, by promoting the usage of fly ash bricks in our construction industry we could enjoy the benefits of this innovative technology and save our environment.

To keep the cost of building materials in reasonable range, we should opt in for alternative building materials like fly ash bricks and hollow or solid blocks.
