Advantages to Builders:
AAC blocks are very light as compared to Flyash and Red clay bricks. AAC blocks (density 550-600 Kg/cum) are roughly one third the weight of the Red clay / fly ash bricks (1800 Kg/cum).
The lesser unit weight helps reduce the dead weight of structure, thereby reducing the steel consumption in high rise structures. Builders can have a substantial cost saving because of this.
Since AAC blocks are porus (porus but pores are not interconnected), they tend to absorb less water while construction.
Apart from that AAC blocks are easy to carry and install saving time and money for the builders.
These advantages make AAC blocks more preferable for builders as compared to the traditional & Fly ash bricks.
Advantages to House Owners:
Since AAC blocks are porus (porus but pores are not interconnected), they tend to act as a good insulation material both for Heat and Sound. This reduces the electricity consumption for Individuals Home Owners.
So Bascially, ACC blocks are
- Resource efficient
- Energy efficient with low thermal conductivity
- Low in water absorption
- Has decent compressive strength say above 65kg/ cm2
