General description
Aerated Autoclaved Concrete (AAC) is a lightweight, high strength, building material used and approved for a variety of applications in commercial, industrial, and residential construction. AAC is also known as aircrete or cellular concrete.

Aerated Autoclaved Concrete (AAC) is a lightweight, high strength, building material used and approved for a variety of applications in commercial, industrial, and residential construction. AAC is also known as aircrete or cellular concrete.

AAC is produced in a variety of forms from blocks, to structural floor and wall panels.

Structural panels are available up to 20' long, 2' wide and from 2" to 12" thick.

Structural panels can be designed as floor, wall or roof structural elements. Lintels and other specialized shapes.

AAC is produced from the common materials lime, sand, cement and 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.

AAC begins as a slurry mix of lime, sand, cement and water, and a small amount of rising agent.

For reinforced panels, a welded steel cage element is placed into the molds prior to pouring in the slurry.

Once the slurry is poured in, the mixture begins to foam and rise up completely around the reinforcing cage.

Once the rising process is complete the
cage and the AAC are completely integrated and ready to be placed into the autoclave for the curing process.

Here is why Autoclaved Aerated Concrete beats all other materials hands down!

Fire Resistant / Non Combustible
AAC is non-combustible. AAC offers the greatest fire resistance of any building material currently on the market. Fire resistance tests carried out by Underwriters' Laboratories have shown a minimum 4" thick non load bearing, or 6" thick load bearing wall, without any finishing materials, provides a 4-hour fire rating. This far exceeds the requirements of the Standard Building Codes and provides a level of protection against loss of life and property that conventional construction cannot approach. AAC also exceeds in the very critical fire hose tests. For builders, the use of AAC eliminates the need for applying costly fireproofing materials. Additionally, no toxins or dangerous gasses are emitted when AAC is subjected to extreme heat.

AAC construction considerably reduces risks to insuring agencies and may be eligible for about 25% less in premiums.

Lightweight
AAC is lightweight. Depending on the exact product, AAC can weight as little as one-fifth the weight of standard concrete, which results in lower transportation costs, faster workflow, lower material handling costs, and fewer work-related injuries. AAC is a "ready to build" material, requiring no on site curing time.

Durable and strong
Successfully used for many years all over the world, AAC was originally invented specifically for load-bearing applications such as wall and lintel construction. As its usage became more commonplace, AAC found acceptance among professionals as a superior building material. AAC can also be used in non-load bearing applications such as sound barrier walls, fire walls and fencing. AAC is excellent for hot to very cold environments, and is recommended and approved for use in hurricane prone areas.

Superior Thermal Insulation
Inherent insulation. AAC has extraordinary thermal insulating qualities. A low thermal conductivity (U value) combined with the thermal mass effect results in a 10" wall that yields an R-31 equivalent rating. That by far outperforms wood and concrete masonry. Consequently, AAC lowers energy costs for cooling and heating, and makes the use of additional thermal insulation unnecessary.

Design Versatility & Flexibility
Unlimited workability. AAC can be sawn, drilled, nailed, screwed and milled with common hand tools. Much like wood, AAC openings are easily and accurately cut. Field adjustments can be made easily. Chases for wiring and outlets can easily be accomplished precisely. The dimensionally accurate panels are finished with a very thin mortar joint, producing a surface that requires minimum rendering.

Excellent Acoustic Insulation
AAC serves as an exceptional acoustic insulation material. Its porous structure and high surface mass, coupled with its ability to dampen mechanical vibration energy, make for a building material that provides an outstanding defense against noise pollution. AAC has a sound insulation value of 7dB (per sq. ft. of surface area) greater than other materials of the same weight. An 8-inch AAC wall has a Sound Transmission Coefficient (STC) of 50. Hotels, multi-family housing, residence halls, and hospitals have benefited from this unique property. Few materials can offer the sound suppression qualities of AAC when it is used as a party wall system or a building envelop.

Reduced Time & Labor Costs
Fast installation – quicker customer payback
No furring, insulation or drywall needed.
Panelized AAC products have a dramatic impact on the material’s rate of installation. An experienced four man team with a crane can install panels at 4-6 minutes per pane. Wall and floor panels are both easy to use and quickly installed, thus enabling a standard crew to install more than four times the square footage of AAC than that of a regular masonry application in the same period of time.

Environmentally Friendly
Aerated Autoclaved Concrete is made from sand, lime, cement, water, and a rising agent. The manufacture and use of AAC generates no pollutants or toxic agents. AAC contains all natural ingredients, and is its self free of pollutants and toxic materials as well. AAC is a "Green" building material capable of greatly reducing the environmental consequences of the demands for traditional construction materials.

Termite and Pest Resistant
There are no voids for insects / pests to make homes. Termites or insects will not attack AAC Concrete products, nor can AAC be penetrated by termites or insects. This feature reduces the need for pesticides while maintaining maximum protection against damage to the building and contents. Due to the unique structure of AAC, it is resistant to mold and mildew as well. The net result of building with our components is a home environment that is exceptional, not just adequate. There is reduced or eliminated exposure to things like mold, termites, fire, formaldehyde, pesticides and other poisons such as those that are used to keep wood from rotting like CCA.
