                  1.  SIMPLE INTRODUCE       Areated concrete brick (light brick ) is the light and porous buidling material. It has light keeping temperature cant burn and other advantages.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.AUTOCLAVED AERATED CONCRETE COMMON CONCEPTION         Common concrete density is usually 1600-2400kg/m3,but Areated concrete are 500kg/m3,600kg/m3,700kg/m3.It has not the big grain,main use silicon material (for example:coal 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 coal 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%. 3.DETAILED PRODUCT DESCRIPTION foam block machine, aerated autoclaved concrete plant, AAC block,aac production line,aac plant,AAC brick,autoclave aerated concrete block,concrete block machine,light weight block   1        Product weight is according to 600kg/m3 to control. 2        annual capacity 200,000M3. 3        set raw  material proportion: cement 6.5%, raw lime 23%, flyash 68%, gypsum 3%, aluminum paste powder 350g/M3. 4        water and material rate 0.631 5        one mould product 2.88M3 6        Casting slurry cycle time 5-6 minutes, cut cycle time 5 minutes. 7        casting slurry temperature 38-42 degree 8        body quiet stop.

    Construction Benefits   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.                   keyword:   aac/aac block making machine/ aac plant/ aac block plant/low price aac block plant/low price
