AAC Blocks

What is AAC block?

Autoclaved aerated concrete is producing concrete masonry unit (CMU) which is, lightweight, durable, load-bearing, and high-insulating building product. It is composed of quartz sand, calcite, gypsum, lime, cement, aluminum powder and water. It is available in wide range of sizes and strength.

 

Why Should We Use The AAC Block In Building Construction?

· AAC blocks are suitable for the high rise buildings. If we use AAC for building construction, it requires less steel and concrete for structural members.

· The lower number of joints requires for AAC block, therefore the required quantity of mortar is less.

·   AAC blocks are suitable in areas with extreme temperatures, due to their property of thermal insulation.

· They are leading to faster construction.

 

Advantages of AAC Block

·  They help to improve thermal efficiency and reduce the heating and cooling load in buildings.

·  Their porous structure provides superior fire resistance.

·   Due to their workable property, they permit accurate cutting, so that the generation of solid waste during use can be minimized.

·  Due to their light weight, they can be easily handled as well as saved cost and energy in transportation, labor expenses.

· The sizes of AAC blocks are larger which leads to faster masonry work.

·  They create at least 30% less solid waste than traditional concrete as well as there is a decrease of 50% of greenhouse gas emissions.

· This material is airy and allows diffusions of water.

· They are good moisture resistance and reduce humidity in building.

· They are long-lasting and eco-friendly.

· They have high compressive strength, soundproof, and non-toxic.

 

Disadvantages of AAC Block

·  In rainy weather, AAC crack after installation. By ensuring the blocks are dry, cracking can be reduced.

·  They are brittle in nature, they should be handled carefully.
