66% Lighter
Greatly reduces foundation dead load when compared to red clay brick.
Ultimate Fire Safety
Highest fire-resistance ratings per inch — zero combustion.
Thermal Efficiency
Drastically reduces HVAC tonnage and lifetime operational costs.
Strength
Compressive strengths available in 3, 4, and 6 N/mm² grades for structural design flexibility.
Pest Control
Inorganic AAC composition resists termites and rodents, reducing pest-control maintenance exposure.
Reduction in manpower
Larger, lighter blocks accelerate laying and reduce mason handling effort versus red clay brickwork.
Manufacturing Workflow
The Manufacturing Process.
01
Storage Silos (Cement & Flyash)
Raw materials including cement and fly ash are securely stored in high-capacity industrial silos, ensuring a continuous supply chain for massive production runs.
02
Mixer
The raw materials are transported into the heavy-duty industrial mixer where they are meticulously blended with water and aluminum powder to form a uniform slurry.
03
Batching Control Panel
An advanced, fully automated batching control panel manages the exact weights and proportions of the slurry, ensuring zero human error and absolute consistency across batches.
04
Primary Cutting
The green block is moved to the cutting line where high-tensile steel wires make the primary horizontal and vertical precision cuts.
05
Autoclave Process
The blocks are loaded into massive industrial autoclaves where they are cured under high-pressure steam (1.2 Mpa) at 185°C for approximately 12 hours.
06
Cured Blocks
The finished AAC blocks are extracted from the autoclave, having achieved their maximum compressive strength, and are transferred to the store yard ready for dispatch.

Material Science
The Anatomy of Strength.
Composition Layer 4 of 4
Aluminium Powder : 0.03% - 0.04%
The gas-forming agent responsible for AAC's cellular structure. When aluminium reacts with calcium hydroxide in the alkaline slurry, hydrogen gas is released, creating millions of fine pores throughout the material. After curing, the block contains roughly 70-80% air by volume, giving AAC its lightweight nature, thermal insulation, fire resistance, and acoustic performance.
70% - 80% air by volume
Post-reaction composition
Composition Layer 1 of 4
Flyash : 65% - 75%
An indispensable by-product of Thermal Power Plants, forming the primary bulk of the block. Consuming this industrial waste mitigates a massive environmental threat — the country produces 60 million tonnes annually, of which only 5% is currently reused.

Composition
Chemistry That Performs.
Every raw material is sourced to strict specifications. The precise proportioning of fly ash, gypsum, lime, and aluminium paste is what differentiates certified structural AAC blocks from ordinary commodity blocks.
