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.

Fly Ash Utilization in Making Concrete

For concrete manufacturers, the usage of fly ash is their big deal because they use fly ash as a component in the range of 10 to 25% for making concrete mixtures. Because of beneficial use in concrete structures, the Environmental Protection Agency (EPA) is reassessing the classification, storage, disposal and reuse of fly ash to ensure that it is properly managed to minimize potential harm to human health and the environment.

Disposed fly ash from thermal power plant is then used for various purposes. Certain classes of fly ash (wet or dry) are an important component of reinforced concrete, the best composite structural material.

Role of Fly Ash in Concrete Structures

Worldwide, concrete is used in the construction of bridges, buildings, roads and so on. Usage of concrete has never been omitted in the construction project. In simple words, concrete support our infrastructure.

More than 75% of all concrete is made with fly ash. Fly ash is specified for all concrete structures in some states. And the concrete industry is only one of the important entities using this abundant waste material. The reason, recycled fly ash goes into making concrete is it delivers measurable economic and structural benefits. Its worldwide availability, strength, durability and relatively economical cost create a constant demand for fly ash in the construction industry.

 
Beneficial uses of Fly ash

Fly ash is a CCP (Coal Combustion Products) possessing unique characteristics that allow it to be used ton-for-ton as a substitute for portland cement in making concrete. Through the reuse of fly ash, the GHG (green house gas) emissions associated with the production of portland cement are avoided."

Future for Fly ash

After few decades of reducing the environmental impact of portland cement production and providing a means of recycling industrial waste, fly ash and concrete stand strong together.

Environmental Benefits of Fly ash used in Concrete

Use of fly ash in concrete imparts several environmental benefits and thus it is eco-friendly. It saves the cement requirement for the same strength thus saving of raw materials such as limestone, coal etc required for manufacture of cement. Use of fly ash reduces area requirement for pond, thus saving of agricultural land.

We manufacture a wide range of construction machinery like concrete hollow block machines, fly ash brick making machine, tiles making machines, pan mixture, concrete mixture machines, CLC lightweight machine and batching plant system with high quality standard.
