Detailed Product Description

AAC Plant

Short for Autoclaved Aerated Concrete Plant

Brief Introduction of AAC Product

1. Aerated concrete brick is a light and porous building material. It is based on cement, lime, slag, fly ash, sand and made of materials such as gas as raw material.
2. It has the features of being light, keeping temperature, cant be burn, good insulation and others.
3. It can be made into many kinds of sizes e.g 600×200×100, 80×80×180, 240×115×53 and 600×200×125.
4. They could be used in industry building and common building. As one of the earliest and most widely used materials, they are more and more popular in the world and they will replace the Clay brick completely.     

Main Features of AAC Product

A.  Light weight

Aerated concrete density is usually 400-700kg/m3, it is about 1/3 of the clay brick weight and 1/5 common concrete block weight. Using the Light brick can reduce the weight of the building and also reduce the loading of the beam of roof and pillar. You can see, it can save the material and cost, it also fight against shaking.

B.   Keeping temperature

It has many porous, the heat transition coefficient is 0.9-0.22W/ (mk), it is just about 1/4 or 1/5 of clay brick, so it is the best materials for keep the room temperature now in the world.    

C. Raw material available widely

There are many kind materials even waste material can be used to produce AAC products, for example: coal ash, sand, waste mine material, coal stone, stone dust, and other silicon materials. 

D. Saving land and energy

When you produce AAC products it use the energy (or fuel) just 11% of the clay brick Products. 

E.  The feature of Plasticity

The AAC Products has one useful advantage is the “Plasticity”. As it is has more foam inside and the weight is lighter and not so hard so it is easy to be produced in every kind shape and when it is re-assemble or re-production it will be more suitable for sawing, paring, drilling, and clinch (clench).

F. Sales Profit

AAC Products’ market profit is bigger than common bricks and cement blocks, especially the AAC Board products (Plate shape AAC Products).

Application

AAC brick is applied widely in the world, especially in below conditions and places.

1. 1^st Youth Olympics Games in Singapore
2. Pakistan Flood of 2010
3. Russia Fire
4. Hainan province flood in China
5. In the earthquake of Indonesia and New Zealand
6. Infrastructure in Iraq and Afghanistan
7. 16^th Asian Games Guangzhou
8. EXPO 2010 Shanghai
9. Infrastructure of America
10. London 2012 Olympic and Paralympic Games

Quality Requirements of Raw Materials

1, fly ash Fly is the core of this product materials, aerated concrete is the main source of Si-Al components. Should be consistent with (JC409-91) standards (see table below) The above requirements apply to the general quality of fly ash (CaO ≤ 10%).

2, cement
Cement fly ash aerated concrete is a major source of strength. Aerated concrete for the provision of the main calcareous material. Applicable to the production of fly ash aerated concrete cement, primarily to cement variety and choice of two sides of labeling.

3, Lime
Lime fly ash aerated concrete is produced by one of the main raw material. Its main role is to provide an effective and cement with calcium oxide to thermal conditions in the water with the siliceous material of SiO2, Al2O3 role in the production of hydrated silicon Calcium. Therefore, products of lime is the main source of strength.

4, gypsum
Gypsum in the fly ash aerated concrete, the process is made gas regulator. The regulating role of gypsum mainly reflected in the lime slurry digestion and thickening of the slow speed. Gypsum is the main chemical components of CaSO4. At present, the plaster on the market there are three:gypsum, anhydrite and plaster. In addition, the production process in the chemical waste gypsum is also produced. Such as emissions from phosphate fertilizer production. Phosphogypsum, fluorine chemicals, fluorine emissions from the production of gypsum, titanium dioxide production of titanium dioxide from gypsum and so on. These low-cost gypsum can be used to replace natural gypsum, reduce production costs. In addition, the ceramics factory of waste gypsum model can also be selected.

5, the air-entraining agent
Fly ash aerated concrete filling material must be made as a gas to make the concrete have a stoma, in order to form a porous structure of light.

6, stable foam
Gas agent, as the thin bubble wall, the interference in a variety of conditions, sometimes easy to rupture the bubble out, affecting the quality of concrete, there is a need to join the slurry of foam stability. WD-88-based compound stabilizer used mainly for filling of the pouring of concrete slurry, at the same time it also has a certain role in foam stability, foam stability can be used to enhance the role of stable foam.
