What is the life of AAC block?

Fire resistance – AAC blocks can offer fire resistance of up to 7 hours (8” wall), based on their core thickness. On the other hand, red clay bricks can provide close to 2 hours of fire resistance.

Is AAC block good for load bearing?

AAC blocks can be used both in load bearing walls as well as non-load bearing or partition walls. Their maximum use is being made in RCC-framed structures where these blocks fill up the wall panel spaces between column and beam network.
