About AAC
Autoclaved Aerated Concrete is a Lightweight, Load-bearing, High-insulating and Durable building product, which is produced in a wide range of sizes and strengths. AAC Blocks is lightweight and compare to the red bricks AAC blocks are three times lighter. AAC is produced from the common materials lime, sand, cement, water, and a small amount of rising agent. After mixing and molding, it is then autoclaved under heat and pressure to create its unique properties. AAC has excellent thermal insulation and acoustic absorption properties. AAC is fire and pest resistant, and is economically and environmentally superior to the more traditional structural building materials such as concrete, wood, brick and stone.

Environmental Benefits |
one clay brick consumes 3kgs of soil |
No soil used, uses fly ash from thermal plants |
Maintenance |
High |
Less due to superior properties |
Pest & Termite Resistance |
Low |
AAC blocks are inorganic, insect resistant and solid wall construction material. Termites and ants do not eat or nest in AAC blocks |
Wastage during construction |
10-15% |
1-2% wastage and can be cut with an axle blade as needed |
Construction Benefits |
Low |
8 times bigger than red brick results in lesser joints, less mortar and high labour cost savings |
Savings in plaster |
No Savings |
35% reduction |
Cost SavingsThe reduced deadweight results into reduction of the use of cement and steel which helps great in cost savings. As the block size is larger size reduces labor cost with lesser joints
|
Environmental FriendlyAAC is a non-toxic product which does not pollute the air, land or water. The manufacturing process does not use sand and creates no by-products or toxic waste products. No more Sand mining.
|
Pest Resistant Consist of the inorganic material in its constitution that helps preventing/avoiding termites, damages or losses.
|
The reduced deadweight results into reduction of the use of cement and steel which helps great in cost savings. As the block size is larger size reduces labor cost with lesser joints
|
Because of the its superior cellular and discontinuous micro structures, AAC walls provide higher resistance to water penetration
|
The thermal conductivity of the AAC blocks helps maintaining the inner temperature to be war during winters and cool during the summers which ultimately gives energy efficiency
