General Aspects


AAC Block

Clay Brick

Structural Cost

Steel saving up to 15%

no such saving

Cement Mortar for Plaster & Masonry

requires less due to flat, even surfaces & less number of joints

requires more due to irregular surface & more number of joints

Breakage & Utilization

negligible breakage almost 100% utilization is possible

average 10 to 12% breakage, so 100% utilization is not possible

Construction Speed

Speedy construction due to it's big size, light weight & ease to cut in any size or shape

Comparatively slow

Labour Output

approximately double of conventional brick

comparatively low


Uniform & consistant

Normally varies


No such chance, which improves the durability of wall along with plaster & paint in a long run

most chances are there

Fitting & Chasing

all kind of fitting & chasing possible (as per IS : 1905)

all kind of fitting / chasing possible


Readily available at any time & any season in a short notice so no storage required

Particularly in monsoon, stock at site is compulsory which block large working space

Water Required

requires less in wetting & Curing, hence saving in electricity bill & labour cost.

need more curing resulted to higher amount of electricity bill & labour cost.

Energy Saving

Approximately 30% reduction in air- conditioned load for both heating & cooling

no such saving


Less due to its superior properties

Comparatively high


The company is the trusted Manufacturer, Exporter and Supplier of durable Autoclaved Aerated Concrete Blocks. For the manufacturing of our Autoclaved Aerated Concrete Blocks, we make use of high quality raw materials and advanced techniques. We make available Autoclaved Aerated Concrete Blocks in bulk and at the most affordable rates. Also, we ensure timely delivery of the orders.

More About Autoclaved Aerated Concrete Blocks : In 1914, the Swedes formulated a mixture of cement, lime, water and sand that expanded due to aeration upon addition of aluminium powder. A material like wood but without the disadvantages of combustibility, decay and termite damage was obtained. The material was further developed to what we know today as Autoclaved Aerated Concrete (AAC). Autoclaved Aerated Concrete (AAC) is a fully integrated building system of panels and blocks that are used for residential, commercial and industrial buildings. AAC, a light-weight green building material, is fire resistant and has good thermal insulation, solid structure and is easy to work with. AAC is manufactured by about 200 Plants in 35 countries and is used extensively in residential, commercial and industrial buildings.

Basic Facts:

  • Its lightweight reduces the dead weight of the structure drastically. Studies show a reduction in foundation steel by 15% and cement 10% if AAC blocks are used.
  • AAC blocks are approximately 9 times larger than clay bricks, which translates into 5 times faster construction & considerable saving in mortar & Plaster.
  • Highest thermal rating in the industry R30! It provides well insulated interiors, keeping out warm air in summers and cold air in winters. AAC reduces air conditioning cost by up to 30%.
  • Use of thinner blocks (6? instead of 9? exterior walls) because of its excellent water barrier & insulation properties leads to an increase in floor space area between 3-5%.
  • AAC Blocks are energy efficient and have been certified by the green building council (IGBC) as green building material and is eligible for leed credits. What’s more in today's world plagued with global warming.
  • It's one of the most versatile building materials. It can be nailed, drilled, chiseled & cut in any way you want. Plumbing & Electrical conducting is very easy.

Details of Merits are being Provided Here Under
High Thermal Insulation :

  • These blocks have appox. 1/3rd density that of conventional building blocks.
  • It has very low specific conductivity, which makes heating or cooling (Air Conditioning) very efficient.
  • Generates regular saving on energy and global warming

Light Weight : With an approximate density of (550 to 650) kg/M3 of AAC which is equal to 1/3 lighter than clay brick hence it reduce dead load of structure drastically resulting in to saving of steel up to 15% and concrete up to 7%. This saves construction time and the total less materials required for the construction of the entire buildings.

Superior Fire Resistance : A 10 cm thick AAC Thermalite block provides a fire resistance value of 4 hours and 15 cm block 6 hours in accordance with BS-5628-3-approximately twice more protection than the normal concrete. Therefore, Thermalite is particularly suited for fire walls and fire protection of structural steel.

Compressive Strength : The block has an average compressive strength of (25-35) kg/cm2 which is superior to most types of light weight blocks, 25% stronger than other producers of the same density.

Workability : It can be sawed, nailed and drilled easier that wood, by suitable tools available for this purpose. It results in less wastage and keeps the site clean.

Economical, Easier & Quicker to Install : Construction time substantially reduced while ECO Bricks blocks are used. AAC Blocks are larger and lighter than conventional blocks and hence can be installed at quicker rate. Blocks are laid flush utilizing thin joint mortar hence reducing mortar and plastering cost and eliminating thermal bridging.

Sound Insulation and Absorption : The Cellular Structure of AAC blocks provides superior sound absorption and insulation, both of which depend on density and porosity. The air porosity of the material will have significant effect on the performance of the wall. The aerated structure of thermalite consists of millions of very small non-interconnected air cells giving very low air porosity. This gives a high resistance to the passage of air borne sound relative to density.

Earthquake Resistance : Due to the stability & Light weight of AAC blocks the structure made from eco bricks are more resistant to earthquake. AAC blocks are better choice in earthquake prone area of south part of India.

High Resistance to air and water penetration : The AAC Products, because of their cellular and discontinuous micro structure are superior to the normal concrete in resistance of water penetrability & thus the external surface of AAC walls provides superior resistance to air and moisture penetration than the traditional masonry products. AAC is manufactured from non-biodegradable materials, which neither rot nor attract mould keeping interiors clean and durable.

Durability & Dimensional Stability : The AAC Products have been in use for nearly 70 years. Since then, the production has spread to most parts of the world and the material has proved its durability under extremely different climatic and chemical conditions. The linear expansion coefficient of Thermalite is approximately 0.02%.
