AAC Blocks

AAC Blocks

We are prominent supplier of Autoclaved Aerated Concrete (AAC) products. Our pre-casted lightweight ACC blocks are increasingly becoming building material of choice for architects, engineers, builders and home owners. Made primarily from fly ash, these are appreciated as 100% green solution and also offer an easy to install as these can easily be routed, sanded and cut to appropriate size.

Earthquake Resistant

Structures made from AAC are light in weight and absorb the shock well, hence these offer high resistance to earthquakes. In addition to these, it is also very effective in major storms. Results have proved that the concrete structure made with AAC can easily endure the wind loads of category 5 tropical storms. For these reasons, ACC is widely used in high seismic zones and storm prone areas.

Floor Space Area

As our ACC provide same strength in thinner exterior walls( 6" instead of 9" exterior walls). It offer more floor space area(about 3% to 5%) without loosing any strength when compared to wider concrete walls.

Cost Savings

As ACC is very light in weight is reduces the overall dead-weight of the building. This helps in reducing the requirement of steel(up to 27%) and cement requirement(up to 20%). Further, as our ACC blocks are 8 times the size of a normal brick, there are only 1/3 joints in comparison. Hence requirement of mortar reduces by 66%. Hence help in saving cement requirement to join two blocks together by 20%.

Moreover, manufactured using advanced technology, our blocks are very smooth surfaced and dimensionally accurate. This allows for final 6 mm skim coat (putty/ POP) to give smooth surface , thus eliminating the requirement of three coat of plaster walls paints.

Water Barrier

It does not allow capillary action and hence provide very effective water proofing in situation where structure are in consistent contact with water such as tanks walls. Water proofing can further, increased by adding silicone based additives.

Pest Resistant

Made of inorganic minerals, ACC is highly pest resistant and does not promote molds and termites.

Thermal Insulation

Our ACC blocks are highly acclaimed for high thermal resistance. With high thermal rating of R30, it provides effective insulation against hot summer and cold winter winds. Therefore, reducing the cost of air-conditioning costs by 30%.

 Fire Resistant

With high melting point of 1600°C , our ACC has fire rating of 4 hours. This is more than twice for regular buildings made of normal concrete, which have melting point of 650°C.

 Sound Proof

AAC wall has an excellent Sound Transmission Class (STC) rating of M and hence provide quite and soundproof interiors.

Energy Efficient

AAC is made using fly ash(up to 65%), which is waste material produced in thermal plants, unlike normal bricks which is made using upper layer fertile soil of agricultural land. That causes soil degradation as land is left barren and unfit for any type of vegetation. Thus ACC is 100% green building material & is a walling material of choice in LEED® certified buildings ( ITC Center, the highest rated green building has been built using AAC) AAC is most energy & resource efficient in the sense that is uses least amount of energy & material per m3 of product.

High Strength

Manufactured using high pressure steam-curing autoclaving process, our AAC have excellent strength to weight ratio, higher than even M 150 concrete, and far exceeds the Indian Building Code Requirements.

DO'S & DONT'S WITH AAC MASONRY:

 Quick Facts Autoclaved Aerated Concrete (AAC):

• AAC Consists 80% air by volume, making it lightest available Walling Material (weighs 1/4" that of clay bricks)
• Formed as a result of reaction of Aluminum on a proportionate blend of Lime, Cement & Flyash, the hydrogen gas that escapes creates millions of tiny air cells giving it a strong honeycomb like structure
• It is further strengthened by High pressure steam curing in Autoclaves.
• Invented in 1923, AAC now accounts for 40% of all construction in UK & 60% of all construction in Germany.
• The rise in demand in India has been so phenomenal that in last 3 years the production has increased by almost 500%!

No wonder, AAC is termed as the Building Material Innovation of the Century!
