Why burnt clay bricks are not sustainable?

Why burnt clay bricks are not sustainable?

While fired clay brick has certain inherent, sustainable properties (e.g. durability, high thermal mass, and, often, local extraction and manufacture [3]), the kilning process fundamental to its manufacture has raised some sustainability concerns because of energy consumption and greenhouse gas (GHG) emissions.

Which one is better AAC blocks or bricks?

Autoclaved aerated concrete (AAC) blocks are eco-friendly, lightweight, and all-weather construction materials that are designed to offer superior performance and durability. They are eight to nine times the size of a traditional red clay brick and provide better compressive strength across all construction projects.

Why are burnt bricks used in construction?

Fire Bricks: After it is burned, it can withstand extremely high temperatures through its fire resistance properties. This is all done without affecting the desires, shape, size, and compromising strength.

What is CLC block?

CLC Blocks (Cellular Light Weight Concrete Blocks) are made of Cellular Light weight concrete (CLC) or Foam Concrete. Cellular Light Weight Concrete (CLC) is a light weight concrete that is produced by mixing cement and flyash slurry with pre-formed foam.

What is CLC brick?

Cellular Light Weight Concrete Bricks (CLC Bricks)- 6 inch CLC is called as Cellular Light Weight Concrete and it is also called as Foam Concrete. Cellular Light Weight Concrete (CLC) is a version of light weight concrete that is produced like normal concrete under ambient conditions.

What are clay bricks burnt in?

It is during the firing that the bricks receive their strength. In the presence of high heat, the alkalies in the clay, together with small amounts of oxides of iron and other metals, are joined in chemical union with the alumina and silica in the clay to form a dense and durable mass.

What are the advantages of CLC blocks over red clay bricks?

In CLC Block there is no top soil consumption and it emits very low Carbon dioxide as compare to Red clay bricks while manufacturing. Chemical mortars can be used for joining the brick. This reduces the material consumption fo cement and also avoids curing process

What is the top soil consumption of clay brick walling?

One sq ft of carpet area with clay brick walling will consume 25.5 kg of top soil (approx). It actually damages environment In CLC Block there is no top soil consumption and it emits very low Carbon dioxide as compare to Red clay bricks while manufacturing. Chemical mortars can be used for joining the brick.

What are the cost savings of using clay bricks for carpeting?

So no significant cost savings One sq ft of carpet area with clay brick walling will consume 25.5 kg of top soil (approx). It actually damages environment In CLC Block there is no top soil consumption and it emits very low Carbon dioxide as compare to Red clay bricks while manufacturing.

Is fired clay brick sustainable?
