Item | Features | Details |
1 | Lightweight | Autoclaved Aerated Concrete panels/blocks are one-fifth of the weight of concrete and are produced in easily handled sizes. (Dry density grade is 525KG/m3) |
2 | Economy | Using AAC panels can shorten the construction period in half because of its lightweight and easy workability. In most cases the need for supplementary insulation can be avoided. |
3 | Energy-saving (Thermal conductivity is 0.11) | Thermal conductivity of Autoclaved Aerated Concrete panels is one-tenth of that of concrete, that means insulated features are 10 times than concrete. Thermal insulation for AAC panels of thickness 100mm is equal to clay tile wall of 300mm. Therefore, AAC panels are building materials with excellent features of thermal insulation. |
4 | Sound insulation | Sound insulation for Autoclaved Aerated Concrete panels of 100mm is 40.8db, while 150mm is 45.6db. There are a lot of separate crystal-shaped blowholes in the panel, so the panel has the features of sound insulation and acoustic absorption. |
5 | Fireproofing (4 hours) | The fire-resistant time for AAC panels of 100mm is 3.42hours while 120mm is 4 hours. The original materials of AAC panels is totally inorganic and is incombustible, and will not volatilize noxious gas even under the high temperature. The product is especially suited for fire-rated applications. |
6 | Load bearing | The intensity of pressure for cube is more than 4mpa. The load bearing capacity for one point is more than 1200N. The rebars within AAC panels are made according to computer calculating force. As a non-loadbearing cladding, AAC panels can be used under circumstances of pressure. |
7 | Anti-vibration | As a building envelope, AAC panels are known for their excellent anti-vibration by architects. In a simulated earthquake experiment (seismic intensity 10.5), none of the panels fracture, and joints of test construction are undamaged. |
8 | Environmental protection | The Autoclaved Aerated Concrete is designed for consumers who are environmentally conscious. It helps reduce at least 30% of environmental waste, decrease over 50% of greenhouse radiation and over 60% integrated energy on the surface of brick. |
9 | Durability | AAC panels are buiding materials of inorganic silicate and not affected by harsh climatic conditions and will not degrade under normal atmospheric conditions. The service life matches with all kinds of construction. |
10 | Efficiency | The Autoclaved Aerated Concrete product’s lightweight and easy workability means it is very quick to install on site, and the construction period will be shortened in half. |

1. What is Autoclaved Aerated Concrete?
Autoclaved Aerated Concrete (AAC) is a lightweight concrete that is formed into blocks and panels for a wide range of loadbearing and non-loadbearing construction applications. It is manufactured from silica sand, cement, recycled material, lime, gypsum, aluminium paste and aerating agents. It is moulded, cut and steam pressure cured in an autoclave before being packed, ready for transport.
2. Is Autoclaved Aerated Concrete a new building material?
Aerated Concrete Autoclaved (AAC) is an amazingly innovative building material that has been used in Europe for more than 80 years and in the US for more than 15 years.
3.Where has Autoclaved Aerated Concrete been used?
It can be used ranging from low rise industrial/commercial developments to high rise offices or medium density residential buildings.
4. Is Autoclaved Aerated Concrete a load bearing material?
The intensity of pressure for cube is more than 4mpa. The load bearing capacity for one point is more than 1200N. The rebars within AAC panels are made according to computer calculating force. As a non-loadbearing cladding, AAC panels can be used under circumstances of pressure.
6.What are the benefits of Autoclaved Aerated Concrete over other building materials?
a.Cost effective - lightweight panels allow for reduced structural components and smaller lifting equipment.
b. Excellent thermal resistance performance.
c. Acoustic performance - effective sound transmission barrier between external and internal environments of the building.
d. Excellent fire rating properties.
e. No wet trades - less mess and a cleaner, safer work area.
f. Less wastage - significantly reduced waste as panels can be custom-made to length requirements.
g. Fewer waste bins and less crane movements.
h. Design flexibility - panels can be easily cut and routed to suit design requirements.
i. Panel lengths up to 6 metres.
j. Strong, secure and durable with corrosion protected steel-reinforced panels.
