AAC Blocks

Category: Walls & Flooring


AAC Blocks ( Autoclaved Aerated Concrete Blocks ) are made using slurry mix containing cement, sand, lime and aerating agent. The slurry is poured and moulded to form lightweight blocks upon which are cured in autoclave. The high pressure steam curing mechanism in the autoclave facilitates the curing process of the moulded lightweight concrete, producing physically and chemically stable products that weigh about 1/5 of normal concrete. AAC blocks contain millions of tiny non-connecting air pockets yielding superior thermal insulation property. They are typically installed to form walls, floors, and roofs.

AAC products are becoming the preferred building products for constructing residential, hotel, industrial and public buildings because of its natural composition and non-toxic property, saves energy and environment friendly. They possess the durability characteristics similar to normal concrete or stone, yet with workability better than wood.

Cost Effective
Speed and ease of installation result in cost savings compared to traditional masonry construction.

History of usage dated more than 50 years protecting building envelopes and remain durable even under extreme weather conditions.

Fire Resistant
More superior than traditional masonry for products with fire resistant up to 4 hours for a nominal block thickness of 100 mm.

Sound Resistant
Scientifically proven to provide better insulation to sound transmitted by air compared with other solid building materials.

Impact Resistant
Wall erected using 100 mm thick AAC products is classified as “Severe Duty” grade and able to withstant impact loads potentially resulting from rough usage.

Good Workability
Can be easily sawn, cut, carved, nailed or drilled using ordinary hand tools.

Thermal Comfort & Energy Saving
Excellent thermal insulation properties result in improved comfort level and saves heating and cooling costs.

Density is about one-fifth of that of normal concrete blocks, making it easily handled.

Water Resistant
Contains millions of closed microscopic cells which strongly resist moisture from passing through.

Dimensional Accuracy
AAC blocks are manufactured under factory environment using state-of-the-art modern machineries resulting in products with tighter dimensional tolerances.
