AAC Blocks vs Red Bricks: Expert Guide by Relgrow
Selecting the right material for your walls is one of the most critical decisions in building a home. While red bricks have been trusted for generations, AAC Blocks (Autoclaved Aerated Concrete) are emerging as a modern, sustainable alternative. At Relgrow, we guide homeowners, architects, and builders to make informed decisions, balancing strength, durability, cost, and energy efficiency. With 15+ years of experience and over 1,000 projects, we ensure your home is built smarter and stronger.
What Are AAC Blocks?
AAC Blocks are lightweight, precast foam concrete blocks made from cement, lime, sand, water, gypsum, and aluminum powder. They are cured in high-pressure steam, creating strong yet light blocks.
Key Features:
- Grey or white blocks
- Larger in size, lighter than red bricks
- Pest-resistant and energy-efficient
- Ideal for modern construction
What Are Red Bricks?
Red bricks are traditional clay blocks used for centuries. Fired at high temperatures, they are solid, durable, and strong.
Key Features:
- Natural reddish color
- Smaller in size, heavier than AAC blocks
- Time-tested in conventional construction
- Require proper quality checks to prevent cracks
AAC Blocks vs Red Bricks: Detailed Comparison
| Feature | AAC Blocks | Red Bricks | Why It Matters |
|---|---|---|---|
| Weight | 8–12 kg per block | 3–4 kg per brick | Lighter blocks reduce foundation load and labor effort |
| Size | 24×8×4–8 in | 9×4×3 in | Larger AAC blocks = faster construction, fewer joints |
| Strength | 3–4 N/mm² | 3.5–5 N/mm² | Red bricks slightly stronger, both sufficient for 3-4 floors |
| Durability | Resistant to pests, shrinkage, cracks | Durable but low-quality bricks may absorb moisture | AAC ensures consistent quality |
| Construction Speed | Faster due to larger size | Slower, more labor-intensive | Time saved = cost saved |
| Insulation | Excellent thermal & sound insulation | Poor insulation | AAC keeps homes cooler, reduces electricity bills |
| Material Cost | ₹60–₹80 per block | ₹8–₹12 per brick | Cost balances out when considering labor and fewer blocks |
| Labor Cost | Lower due to ease of installation | Higher due to small size and slower work | AAC saves both money and time |
| Wastage | Brittle if mishandled | Stronger during transport | Careful handling of AAC reduces wastage on site |
| Eco-Friendliness | Made with industrial waste, energy-efficient | Clay bricks cause topsoil loss and pollution | AAC is greener and sustainable |
Cost Comparison Example – 1000 Sq Ft Home
- Red Bricks: ~35,000–40,000 bricks → ₹3.5–4 lakh
- AAC Blocks: ~5,000–6,000 blocks → ₹3–3.5 lakh
Why AAC Wins: Reduced labor, faster plastering, better insulation, and long-term energy savings.
