Vajrh AAC Bricks —
Built to Last
Vajrh AAC Bricks are manufactured using a state-of-the-art autoclaving process, combining fly ash, cement, lime, and aluminum powder to produce a lightweight yet incredibly strong building block trusted by engineers and architects across India.
Why Engineers Choose
Vajrh AAC Bricks
Every brick is engineered for performance — from thermal comfort to structural durability.
Superior Compressive Strength
With a compressive strength of ≥ 3.5 N/mm², Vajrh bricks deliver robust structural integrity suitable for all types of residential and commercial construction.
Excellent Thermal Insulation
The porous cellular structure of AAC reduces heat transfer significantly, keeping interiors cool in summer and warm in winter — cutting energy bills by up to 30%.
Lightweight & Easy to Handle
AAC bricks are up to 3× lighter than traditional clay bricks, drastically reducing the dead load on structures and speeding up construction timelines.
Outstanding Fire Resistance
Vajrh AAC Bricks offer up to 4 hours of fire resistance, making them one of the safest building materials available — ideal for high-rise and commercial projects.
Precision Dimensions
Machine-manufactured to exact tolerances, Vajrh bricks reduce mortar usage by up to 60%, ensuring faster, cleaner, and more economical construction.
Eco-Friendly & Sustainable
Made using fly ash (industrial waste), Vajrh bricks are an environmentally responsible choice that reduces carbon footprint without compromising quality.

How Vajrh AAC Bricks
Are Made
A precise, controlled manufacturing process ensures every brick meets our quality standards.
Raw Material Preparation
High-quality fly ash, OPC cement, lime, gypsum, and aluminum powder are carefully sourced and tested. Raw materials are batched in precise proportions to ensure consistent product quality in every batch.
Mixing & Pouring
The slurry mixture is prepared in a mixer and poured into large steel molds. The aluminum powder reacts with calcium hydroxide to release hydrogen gas, creating millions of tiny air bubbles that give AAC its signature lightweight structure.
Pre-Curing & Cutting
The expanded "green cake" rests in a pre-curing chamber until it reaches optimal semi-rigid consistency. It is then wire-cut to precise dimensions using an automated cutting machine, ensuring uniform size and shape across every block.
Autoclaving
The cut blocks are transferred to large autoclaves where they are steam-cured at 180°C and 10 bar pressure for 8–12 hours. This process transforms the calcium silicate hydrate matrix, delivering the final strength, durability, and dimensional stability.
Quality Testing & Dispatch
Every batch undergoes rigorous testing including compressive strength, density, dimensional tolerance, and water absorption tests as per IS 2185 Part 3. Only certified bricks are packed and dispatched to project sites.
