Automatic aac block making machinery


We are one of professional manufacturers & supplier of autoclaved aerated concrete (AAC) plants in India, and we can supply complete set of autoclaved aerated concrete plant with 50000, 100000,150000m3 capacity annually (from 166 m3 to 500m3 per day), including plant design, equipments installation, technical instruction, personal training, etc., and also can design and manufacture as per clients' requirement.


 Plant design:

1. Plant area is 7500-15000 m2, and we can make design based on your actual area of land.

2. Plant should have raw materials field and finished products field;

3. Plant should have maintenance workshop, test room, warehouse,etc.

4. The plant construction time (from earthworks to trial operation) is about 6 month.


AAC Block Features

Thermal Insulation

Highest thermal ratting in the industry. Thus provides well insulated interiors, keeping out warm air in summers and cold air in winters. AAC reduces air conditioning cost by 20%. AAC provides superior thermal insulation due to its cellular structure and results in substantial power savings where air conditioned needs is necessary.


Go-Green Nature

Least carbon footprint with a potential offset of 0.8 tonne CO2 per m3. A Green Building material – contributes to LEED rating.


Earthquake Resistant

Earthquake forces on structure are proportional to the weight of the building, hence AAC shows excellent resistant to earthquake forces. Regions of the seismic activities like exclusively use AAC. It has been proven to withstand wind loads of category 5 tropical storms.




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) It is most energy and resource efficient in the sense that it uses least amount of energy & material per m3 of product. Unlike brick manufacturing process which use precious layer too-layer agricultural soil, AAC uses fly ash (65% to 70% of its weight), thus provides the most constructive solution to the nation’s fly-ash utilization problem.



Fire Resistant

Its unique cellular structure provides excellent fire rating. Due to this Cellular structure AAC blocks do not disintegrate even in fire. It is best in class fire rating of 4 hours. The melting point of AAC is over 1600 degree Celsius, more than twice the typical temperature in building fire 650 degree Celsius.


Pest Resistant

With solid wall construction and finishes, there are fewer if any, cavities for insects and rodents to dwell in. Termites and ants do not eat or nest in AAC. Being made up of inorganic minerals, it does not promote growth of molds.

Other Features

Ease of working

AAC can be drilled, sawed, nailed, and chiseled. Basically, one may work Autoclaved Aerated Concrete like wood, using wood working tools.


Faster Construction

AAC's advantages in construction is its quick and easy installation since the material can be routed, sanded and cut to size on site using standard carbon tip band saws, hand saws and drills.


Light Weight

It weighs approximately 1/3 of the weight of normal walling materials. AAC provides significant benefits where weight is a concern in building design. AAC is the perfect material for renovations. It causes dead weight reduction of the building and hence the reduction in structural costs.




Sound proof

AAC wall has an excellent Sound transmission Class (STC) rating of 44. Result virtually sound proof interiors. AAC consists 80% air by volume, making it lightest available Walling Material (weighs 1/4th that of clay bricks). It was formed as a result of reaction of Aluminum on a proportionate blend of Lime, Cement Flyash; the hydrogen gas that escapes creates millions of tiny air cells giving it a strong honeycomb like structure. It is further strengthened by High pressure steam curing in Autoclaves.



High Strength

High pressure steam-curing autoclaving process gives AAC unmatchable strength to weight ratio, higher than even M 150 concrete, and far exceeds the Indian building Code Requirements.


Cost savings

Being light weight AAC drastically reduces the weight of the building. Resulting into reduction in steel (up to 27%) and cement (up to 20%) structural cost savings. Being 8 times the size of a clay brick, AAC wall construction involves 1/3rd of the joints, thus an overall mortar savings 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 6mm skin coat (putty/pop).


Savings in Plaster

AAC blocks have uniform shape and texture, which give even surface to the walls. There is overall 35% reduction in the cost of plastering.



Reduction in wastage due to fewer breakages.

Unlike conventional clay bricks which are prone to breakages, around 25 %. AAC blocks have almost nil breakages.


Reduction in HVAC load

AAC blocks are resistant to thermal variation. They reduce total load of air-conditioning / cooling. Though initial installation cost may remain same AAC blocks reduces operation and maintenance cost drastically. There is overall 25% saving in operation cost.


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%.
