Aerated Autoclaved Concrete (AAC) Blocks
AAC Blocks outperform the concrete and clay bricks with their superior technical properties. AAC offer cost savings, improved quality and high workability alternative to concrete blocks and clay bricks. It can be reliably used for walls, partitions & panels.
AAC begins as a slurry mix of cement, lime, sand, gypsum and Aluminum powder. The mix rises, is cut to specification & baked in high heat autoclave chambers.
The Bureau of Indian Standards (BIS) specifies the Grade I and Grade II AAC blocks.
Why Sand Based AAC?
According to Scientific American magazine, the Fly ash emitted by burning coal in power plants contains 100 times more radiation (uranium and thorium) than a nuclear power plant producing the same amount of energy. It is a occupational hazard for people working with fly ash or within 1.6 KMs of land fills, quarries, abandoned mines where fly ash is dumped.
Benefits of Popular AAC
Light Weight
AAC is far lighter than bricks and concrete. Saves on transport, masonry material and re-inforcement costs. Ideal for multi-storeyed structures with high FSI/TDR.
High Workability
The versatile AAC blocks can be sawed, drilled, nailed, milled, cut easily during construction. It hides cables, conduits, drain/plumbing pipes. Saves due to less breakage.
High Fire Resistance
Air voids within the block and use of incombustible ingredients make AAC blocks resist fire. Use for lifts, chemical plants, textile plants etc.
Earthquake Resistance
AAC conforms to requirement of Seismic zone IV & V and is proven to withstand wind loads of Category 5 tropical storms
Thermal Insulation
Very low thermal conductivity. Useful for walls of Boilers, Heat Plants. Saves Energy and Money for heating and air-conditioning.
Termite Resistance
AAC Blocks use inorganic and termite resistant ingredients and hence cannot be damaged by termites and pests.
Sound Absorption
High sound absorption makes it suitable for sound-proofing requirements of schools, studios, hospitals, places of worship etc.
Water Resistance
Low capillary action and high surface reaction does not allow moisture to seep into the closed cells of AAC blocks.
Green Process & Environment Friendly
Sand based AAC is environment friendly for end-use. The manufacturing process consumes lesser energy, does not emit pollutant gases and recycles material waste.
Dimension Accuracy & Surface Finish
Larger than bricks, AAC blocks ensure rapid construction. Lesser joints saves time and material. Precise dimensions reduce need for filling at joints. Uniform surface finish saves plaster & finishing material.
