Autoclaved Aerated concrete block machine:
What is AAC?
1. Aerated Autoclaved concrete block (light block ) is the light and porous buidling material. 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. it can be made into many kinds of bricks(for example:600×200×100,80×80×180,240×115×53,600×200×125),
they could be used industry building and common building.they are more and more popular in the world.in the future,they will replace the Clay brick completely.
2.Areated concrete common conception
Common concrete density is usually 16002400kg/m3,but Areated concrete are 500kg/m3,600kg/m3,700kg/m3.It has not the big grain,main use silicon material (for example:flyash,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 slop,then add the aluminum dust and the additive.Make the aluminum dust and the special slop have a Chemical reflect.then produce Hydrogen to make the concrete slop to expanding or swell,foam.Next,put them into the curing room to concreting cutting steaming curing,last,there will bacome the light brick,the porous rate is 70-80%.
Feathers of AAC
1.Sound proof
AAC wall has an excellent sound Transmission class (STC) ,rating of 44. Result: Virtually Soundproof Interiors!
2.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%.
3.Earthquake Resistant
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.Cost saving
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.
7.Pest ResistantTermites hate AAC! Being made of inorganic minerals, it does not promote growth of molds.
8.Water Barrier
Its structure does not allow for capillary action making it impervious to water. Its water barrier properties are further enhanced by adding silicone based additives.
strength to weight ratio, higher than even M150 concrete and far exceeds the Indian Building code requirements.
9.Energy Efficient
AAC is 100% Green Building Material & is a walling material of choice in LEED certified buildings (ITC centre, the highest rated Green Building has been built using AAC).AAC is most energy & resource efficient in the sense that it uses least amount of energy & material per m³ of product.Unlike brick manufacturing process which uses previous toplayer agricultural soil, AAC uses FlyAsh (65% of its weight), thus provides the most constructive solution to the nation’s flyash utilization problem.
AAC land and workshop require:
50000m3 to100000m3,workshop is 2000m2,the land is 8000m2,
150000m3,workshop is 2500m2,the land is 10000m2,
200000-300000 m3,workshop is 3000m2,the land is 15000m2.
