What Are AAC Blocks?

AAC blocks are precast, lightweight, foam-like construction materials made from a mixture of sand, cement, lime, water, and aluminum powder. They are cured under high pressure and heat (autoclaving), making them strong, durable, and resistant to fire and pests.

Key Properties of AAC Blocks

1. Lightweight Yet Strong

3-4 times lighter than traditional bricks, reducing structural load.
High compressive strength (3-5 N/mm²), suitable for multi-story buildings.

2. Excellent Thermal Insulation

Keeps interiors cooler, ideal for Chennai’s hot climate.
Reduces AC dependency, saving energy costs.

3. Fire-Resistant

Withstands fire for up to 6 hours, enhancing safety.

4. Soundproofing Qualities

Reduces noise transmission, perfect for urban buildings.

5. Eco-Friendly & Sustainable

Made from natural materials, low carbon footprint.
Less construction waste compared to traditional bricks.

6. Easy to Work With

Can be cut, drilled, and shaped easily, speeding up construction.
Uniform size ensures precise masonry with less mortar.

7. Moisture & Pest Resistant

Resists dampness and mold growth.
Termite-proof, ensuring long-term durability.
