Build Smarter.
Build Stronger.
Premium Autoclaved Aerated Concrete (AAC) blocks engineered for faster construction, lower costs, and a greener future.
Why Choose AAC Blocks?
Better material choices compound into massive savings across the entire structure.
Lightweight & Strong
2.5× lighter than conventional bricks - 66% lighterthan red clay bricks - while matching or exceeding structural strength requirements.
Effortless Handling
AAC blocks are so lightweight, they can be easily lifted and placed by a single worker-reducing fatigue and speeding up construction.
Precision Dimensions
Factory-cut to exact tolerances. Uniform size means faster laying, less mortar, and perfectly plumb walls.
Built-in Safety
Highest fire-resistance ratingper inch. Excellent seismic performance. Inorganic composition -100% termite-proof.
Eco-Friendly by Design
Every LEOCON block is made from a precision mix of pulverized fly ash, lime, cement, gypsum, water, and aluminium - with fly ash making up a full 70% of the composition.
Fly ash is a hazardous by-product of Thermal Power Plants. By making it our primary raw material, LEOCON INFRA converts industrial waste into world-class construction material - reducing the carbon footprint of every building we contribute to.

Batching & Mixing
Coal fly ash, lime, and cement are precisely measured by electronic scales and fed into the casting mixer. Aluminium powder is then introduced - the chemical reaction creates millions of micro-bubbles, giving AAC its lightweight, porous structure.
Pouring & Pre-curing
The slurry is poured into large steel molds and left to pre-cure. The mix expands as aluminium reacts, and the cake achieves enough green strength to be handled without deforming.
Precision Wire-Cutting
The green cake is transferred to a cutting frame and sliced by fine steel wires to exact block dimensions. Factory tolerances ensure every block is identical, eliminating the uneven sizes that slow down bricklaying.
Autoclaving
Blocks are loaded into high-pressure autoclaves and steam-cured for ~12 hours at ~1.2 MPa. This mineralises the block, creating a permanent crystalline bond that locks in final structural strength, fire resistance, and dimensional stability.
