What is the AAC Panel and AAC Block?

AAC Panel is the shortened form of Autoclaved Aerated Concrete Panel. The main materials of AAC panel are silicon sand, cement, lime etc. Reinforced with anti-stain processed steel bar, the concrete panel with many air holes was formed after high-temperature, high-pressure protection with steam. It’s a new type constructional material with excellent functions. There are patents of Germany and Sweden and Japan included in the production equipments. The complete production process, from mixing raw material, anti-stain processing of steel bar, organizing into frame, pouring paste on, cutting, steaming and pressing to surface processing, is calculated accurately with computer program and has a rigid QC control.
AAC Block is the shortened form of Autoclaved Aerated Concrete Block. The difference of the AAC block from the AAC panel are: 1) no reinforced steel inside 2) sizes are smaller than AAC panel.

AAC Production Process

Raw Material Preparation

Mix silica sand, cement, calcium lime, and gypsum, and then add a little aluminum powder to the slurry.

Steel Bar Assembling

Assemble the anti-rust treated steel bars into mesh frames, then put them into the moulds, and pour the material slurry.

Foaming

Chemical reactions begin after the pouring of the slurry. Bubbles appear evenly in the mould structure. The bubbles emerging at the time will determine the performance of AAC panels.

Cutting

After the structure gains its early strength foaming and waiting, cut with piano wires and get the needed length, width, and thickness of the panels.

Autoclave Treatment

Use autoclaves to treat AAC panels and make them hardened in high-temperature and high-pressure steams.

Post-Processing

Decorative patterns will be made on the surfaces of the autoclaved panels that have been treated in autoclaves, according to the customer’s requirements.

Quality Inspection

All panels will undergo strict quality inspection in order that their good quality is ensured.

Delivery

Only products strictly inspected can be delivered.

Features of the AAC panels and AAC Blocks

Lightness

Specific gravity 0.5 Floating on the water
The dry specific gravity of the AAC panel is only 0.5 because it is one kind of foamed concrete. As the above rate is 1/5 of common concrete and 1/3 of hollow block, it lightens the self-weight of building, reduces the cost of base and frame, cuts down the difficulty in process of soft groundsill, and increases the construction quality.

Sound Insulation

A lot of micro and small air holes that are inside the AAC panel cause multi-function of sound insulation and assimilation. The high precision of panel can create a fine air keeping space to supply a silent and comfortable living environment.

Heat Insulation

Rate of heat transmission 0.11 1/10 of common concrete
A lot of micro and small air holes that are inside of the AAC panel form a static air layer in the material and make the rate of heat transmission of only 0.11W/m.K. The function of heat insulation and preservation of the AAC panel is 10 time of common concrete. The function of heat preservation of AAC panel at 125mm thickness is same as 370mm wall of soil-block.

Anti-Vibration

It is world-wide outstanding known of the anti-vibration ability of AAC panel. Only the constructions built with AAC panel are broken lightly at heavy earthquakes at Osaka/Kobe.
The tests in the laboratories of Tongji University and Southeast University in China show that the AAC panel has excellent function of anti-vibration. The light self-weight of AAC is the main cause, as it allows bigger angular distortion between layers and the allowed changing angle is 1/150.

Fireproofing

Panel for wall------ Fireproofing in 4 hours
The AAC panel can stand against fire as the low rate of heat transmission. The self of AAC belongs to abio-compound and is not burnable. It doesn’t produce nocuousness gas. At Tianjin National Fixed Anti-fire System Center, it passed the test for fire bearing of 240 min limit.

Load-bearing

The AAC panel can bear wind load, snow load and dynamic load.
There are following types of the AAC panels:
Outside wall panel , Inner wall panel , Roof panel , Floor panel
The steel ribs inside of AAC panel are arranged by CAD according to loading situation, that the capacity of loading is obtained.
