Full Automatic AAC Autoclaved Aerated Concrete Block / Aac Block Production Line

AAC Block Features:

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.

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%.

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.
