AAC Block Benefits
AAC Blocks are made from cement, lime, fly ash, gypsum, aluminum powder, and oils. The mix is molded and cured under high-pressure steam, creating a lightweight, porous, and durable structure.
These blocks offer excellent thermal insulation, keeping buildings cooler and reducing air conditioning costs. They also lower foundation load and reduce the need for structural steel and mortar, making them a cost-effective and sustainable building solution.

Enhancing The Future With Quality, Precision And Excellence
Earthquake resistant
The effect of earthquake is proportional to the weight of the structure. AAC blocks being a light weight subdues any damage by quakes or high winds largely.
Great ventilation
This material is very airy and allows diffusion of water. This reduces the humidity inside the building. AAC will absorb moisture and release humidity. This helps to prevent condensation and other problems that are related to mildew.

- We keep all the raw materials In silo’s in order to avoid contamination with
outside dust particles - Four Silo’s are used in order to make the process smoother
- Feeder is used to load the lime and gypsum ensuring no manual interference.
No compromise on raw material quality
- We use only OPC Grade 53 Cement in order to give maximum strength.
- Fly ash is preferred over pond ash, as Pond ash has more impurities compared
to fly ash. - Other Raw materials are thoroughly tested before using in manufacturing process.
We are using skada software
- One of the best software used in manufacturing industry
- Entire Batching process is automated in order to achieve consistency.
- Even 0.1% irregularity in quantity of raw material can hamper the quality of
production
In-house testing laboratory
- In-House Testing Laboratory ensures that raw materials and final products meet the required standards and specific ations. This helps in maintaining consistency and reliability of the final production.
Quality checks at every step
- We ensure quality check at every step of manufacturing process, be it Raw Material Inspection, Post Production Testing or Pre – Cast testing etc. in order to maintain quality production.
Hi – tech cutting machine
- In Vajra, we use Hi-tech cutting machine for shaping the large aerated concrete blocks into smaller, precise sizes.
- Zero Percent wastage during cutting process.
- Fully Automated
Keeping environment into consideration
- Dust collector and Bag filters are used in chimneys which significantly reduce
air pollution by trapping and removing particulate matter from exhaust gases. - Zero Percent residue left.
- Mostly used bio-mass fuel in Boiler
