Can we use AAC blocks for load bearing walls?

Can we use AAC blocks for load bearing walls?

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.

What are the disadvantages of AAC blocks?

Disadvantages of AAC Blocks are following:– AAC blocks have brittle nature; therefore, they require more care than clay red brick during handling and transporting. The cost per unit of AAC block is high, but overall, masonry cost is low because it requires less cement mortar for installation.

Are AAC bricks load bearing?

AAC blocks are used for load bearing as well as non-load bearing walls, partition and panel walls, an inner leaf of cavity walls or a backing to brick masonry.

Why does AAC block wall crack?

Some of the reasons behind such cracking are deflection of beams, uneven placing of blocks, structural movements due to Thermal expansion or change in moisture content. One way to avoid this is to delay the use of the blocks till equilibrium moisture content is reached. ... Bond beam must be discontinuous at control joint.

Is AAC block good for home?

Autoclaved aerated concrete is an innovative building material. It has unique properties that make it better than traditional bricks while giving protection to a building structure in many ways. Moreover, it is environment-friendly and saves overall construction cost.

Can we use AAC blocks for a load-bearing wall?

The Compressive strength of AAC block is 3 to 4.

How much weight can an AAC block carry?

Depending on its density, up to 80% of the volume of an AAC block is air. AAC's low density also accounts for its low structural compression strength. It can carry loads of up to 8 MPa (1,160 PSI), approximately 50% of the compressive strength of regular concrete.

Which is lighter red bricks or AAC blocks?

AAC Blocks is lightweight and compare to the red bricks AAC blocks are three times lighter. The Autoclaved Aerated Concrete (AAC) material was developed in 1924 in Sweden. It has become one of the most used building materials in Europe and is rapidly growing in many other countries around the world.

What happens to AAC block after autoclaving?

After the autoclaving process, the material is ready for immediate use on the construction site. Depending on its density, up to 80% of the volume of an AAC block is air. AAC's low density also accounts for its low structural compression strength.
