Light Weight AAC Cement Block Brick Making Machine Production Line
About AAC block :
what is AAc block? Which is made by cement,lime,fly ash&sand,gypsum ...and steam curing finished.It with those characteristics like: light weight,cost saving,earthquake resistant,high strength,water barrier,keep warm,heat insulation,sound insulation,save resources...AAC block as a new building material is making and applicating for so many years in China,and Hngfa now is full experience in making machines and AAC block...
Two point about AAC:
1. Light weight .Areated concrete density is usually 400-700kg/m3,(according the market in produce ),same as 1/3 of clay block and 1/5 common concrete.So use the Light block can reduce the weight of the build more,and also reduce the beam of roof and pillar press best.then you can see,it can save the material and cost,it also fighting shaking.
2. Keeping temperature .It has many are porous,the delivery hearting coefficient is 0.9-0.22W/(mk),the same as 1/4 or 1/5 of clay brick,so it is best materials now in the world.

Advantages of the AAC brock application:
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 Resistant Termites 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 top layer agricultural soil, AAC uses Fly Ash (65% of its weight), thus provides the most constructive solution to the nation's fly ash utilization problem.
Aerated autoclaved concrete block is the light weight and porous building material:
A.It can be made into any size of bricks and steel reinforced blocks:Such as 600*200*100mm,80*80*180mm,240*115*53mm,600*200*125mm and so on.They could be used in industry building and common building.In future,AAC block is an ideal substitute for traditional clay brick.
B.Capacity:from 50,000 cubic meters to 300,000 cubic meters per year.
