WHAT IS AAC BLOCKS? Why is it the popular choice among all now days?

Autoclaved Aerated Concrete (AAC) Blocks is a certified green building material, which can be used for commercial, industrial and residential constructions. It is a durable, sustainable and cost-effective replacement of conventionally used Bricks.

AAC was developed in 1924 in Sweden with a motive to develop a material which had the benefits of workability like wood and durability like concrete. The material hence formed surpassed all expectations and since then it is the most used building material in the European countries and now rapidly growing in other parts of the world.

AAC Blocks are manufactured with Cement, Lime, Silica and Aluminum Powder as major raw materials using highly sophisticated plant & machinery. The AAC Mix is fully cured in Autoclaves using Steam at high pressure and temperature which gives AAC Blocks the highest strength to weight ratio among various commonly using Walling materials.

AAC Blocks are extremely light in weight and with their myriad benefits like High Thermal & Sound Insulation, Big Size, Easy Workability etc are fast becoming the first-choice walling material of Builders & Architects in India as well.

Some of the major benefits that make AAC the preferred choice of material for all are:

Fast & Easy Construction

AAC Blocks are big in size and have excellent workability. The blocks can be easily cut, chased, drilled using hand tools. This enable very fast & easy construction at sites.


Using AAC Blocks makes your building or home extra safe from issues calamities like Earthquake & Fire. The light weight of AAC Blocks reduce the dead load of the building which enables a better safety during earthquakes. The blocks are made of inorganic materials and conform to Class ‘)’ rating for spread of fire and also have the best in class fire resistance.


The unique cellular structure of AAC Blocks provides them with very High Thermal & Sound Insulation. This provides the residents of a building comfort from the outside temperatures and noise.

Environment Friendly

A Sustainable future is only possible with use of environment friendly products for development and AAC Blocks provide that sustainable choice which is much needed for today’s fast paced development.

AAC Blocks utilizes industrial waste as its major raw material as against fertile top soil which is utilized to make the conventional bricks. The Blocks do not require any water curing during masonry which can save lakhs of ltrs of water in each building.


In the cut throat competition that we face today any innovation holds its meaning only if it is cost effective. With proper construction practices and design, AAC Blocks can turn out to be much more cost effective compared to conventional materials which may look cheaper up-front.
