New style AAC Block Production Line / Sand Lime / Fly Ash Block Plant


What is AAC (Autoclaved Aerated Concrete) ?
1. AAC block also called autoclaved aerated concrete block or Light concrete Block. AAC was perfected in the mid-1920s by the Swedish architect and inventor Dr. Johan Axel Eriksson, working with Professor Henrik Kreuger at the Royal Institute of Technology. It went into production in Sweden in 1929 in a factory in Hallabrottet and quickly became very popular. In the 1940s, the trademark Ytong was introduced, and was often referred to as "blue concrete" in Sweden due to its blueish tinge.It used siliceous (fly ash, sand, slag) and calcareous (lime & cement) as the main raw materials, which through the process of batching, pouring, pre-curing, cutting, autoclaving, separating and packing to make into the final products.
2. AAC block is one kind of environmental construction material and widely used for industry and civil building construction. It has light ,keeping temperature , Environmental protection,can’t burn and other advantages. It has a wide prospect of market.it is the main building material in the future.
3.As normally, concrete density is usually 1600-2400kg/m3,but aerated concrete are 500kg/m3,600kg/m3,700kg/m3.It has not the big grain and use silicon material (for example: fly ash,sand,stone dust and others ),through making the material small for example sand, they can be used directly if has enough degree of small (for example fly ash, Mixing calcium material lime, cement, water to a special ratio, then add the aluminum dust and the additive, then Make the aluminum dust and the special ratio have a Chemical reflect. then produce Hydrogen to make the concrete slop to expanding or swell and foam. Next put them into the curing room to concreting cutting steaming curing, At last, there will become the light brick and the porous rate is 70-80%.

How AAC (Autoclaved Aerated Concrete) production line working ?

  1. First of all, dosing of the stored raw materials
  2. Feed raw materials into the pouring mixer and evenly mixing
  3. Poured the slurry into the mould
  4. Static stop and pre-curing under a certain temperature, the slurry become a big block
  5. The big block had a certain of hardness, then be hanged for 90 degree by turning hoister
  6. Open the mould and de-moulding ,The big block will sit on the one side plate
  7. and also 8 :Horizontal cutting the big block

9. Vertical cutting the big block
10. Hanging semi-product to hardening car
11. Entering autoclave
12. hardening
13. leaving autoclave
14. Hanging and stacking of end products
15. loading and packing

Feature of AAC:
1. Thermal Insulation
It has highest thermal rating in the industry….R30! Thus provides well insulated interiors, keeping out warm air in summer and cold air in winters. AAC reduces Air conditioning cost by 30%.
2. Sound proof
AAC wall has an excellent sound Transmission class (STC) ,rating of 44. Result: Virtually Soundproof Interiors!
3. Resistant of earthquake
Earthquake forces on structure are proportional to the weight of the building, hence AAC shows excellent resistant to earthquake forces. Regions of high seismic activity like Japan exclusively use AAC. It has been proven to withstand wind loads of category 5 tropical storms.
4. Floor Space Area
Use of thinner blocks (6" instead of 9" exterior walls) because of its excellent water barrier & insulation properties leads to an increase in floor space area between 3-5%.
5. Saving cost
Being lightweight AAC drastically reduces the dead weight of building, resulting into reduction in steel (up to 27%) and cement (up to 20%) structural cost saving.Being 8 times the size of a clay brick, AAC wall construction involves 1/3 the joints, thus an overall mortar saving up to 66%.
Its automatic manufacturing process gives AAC an exceptional dimensional accuracy & smooth surfaces, eliminating need of three-coat plaster walls and allows for a final 6 mm skim coat (putty/POP).
6. Fire Resistant
Best in class fire rating of 4 hours. The melting point of AAC is over 1600 ºc, more than twice the typical temperature in a building fire of 650 ºc.
