A quick comparison between AAC blocks vs clay bricks
AAC blocks are a relatively new phenomenon in Indian construction industry. Although first AAC blocks plant in India was
set up in early 1970s by Siporex at Pune, it is only recently that manufacturing and usage of AAC blocks has reached
sizeable number. Inspite of drastic growth in manufacturing of AAC products, fact is that market share of AAC products is
very small compared to red clay bricks. There are various reasons for this, but that is a topic for another post. In current
post we have provided a comparison between AAC blocks vs clay bricks and we let you be the judge for selecting the best
product to suit your needs.
Serial Parameter AAC Blocks Clay Bricks
1 Soil Consumption Zero soil consumption. Primary raw
material for AAC blocks is fly ash. This
fly ash is industrial waste generated
by coal-based thermal power plants.
One sq ft of carpet area with clay brick
walling will consume 25.5 kg of top soil.
2 Fuel Consumption One sq ft of carpet area with AAC
blocks will consume 1 kg of coal.
One sq ft of carpet area with clay bricks
will consume 8 kg of coal.

Dear Rajan babu,
Thank you for your response on my website. I am afraid I do not have all the information required to
compute cost of clay brickwork vs AAC brickwork in Chennai. But you may check with local contractor who
has used both clay bricks as well AAC blocks to get more realistic numbers.

Dear Kiran Kumar
Thank you for your response on our website. I suggest that you consult your structural engineer for a
design optimized for using AAC blocks. He would be better placed to suggest you on exact figures for
steel consumption.
