Benefits of Autoclaved Aerated Concrete (AAC) in Construction
Autoclaved Aerated Concrete (AAC) is a lightweight precast form concrete building material. It is composed of quartz sand, calcined gypsum, lime cement, water and aluminium power. Aluminum powder is used at a rate of 0.05%–0.08% by volume (depending on the pre-specified density). AAC products are used under heat and pressure in an autoclave. The various forms of AAC are blocks, wall panels, floor and roof panels, cladding panels and linlels. Autoclaved Aerated Concrete (AAC) blocks are used on both interior and exterior construction works.ACC blocks are provide the structure form fire resistance and insulation.ACC materials are standard tools to cut and shaped to used.It highly recommended for thermally insulating material for both interior and exterior.

Advantages of AAC
- The most important advantage of AAC is its lower environmental impact.
- Improved thermal efficiency reduces the heating and cooling load in buildings.
- Excellent soundproofing material and acoustic insulator.
- Highly fire and termite-resistant.
- Manufactured in a variety of forms and sizes.
- Reduces project cost.
- AAC absorbs moisture from air and releases humidity.
- Installation of electrical and plumbing lines are easy.
- Shipping and handling is more economical.
- AAC is a durable material.
- ACC required less quality of steel and concrete for structural members.
12.Masonry work are faster due to large size of brick.
- Compared to traditional concrete environmentally friendly it produce less than 30% solid waste.
14.Accuracy of the panels and blocks made up of autoclaved aerated concrete are exact size and shape before leave from factory.
15.ACC blocks absorb moisture and release moisture to make a pleasant surrounding.
16.Improve thermal effectively reduce the cooling and heating in building.
Disadvantages
1.Insatallation in rainy weather condition cracks formed after installation to reduce the strength of mortar.
2.Be carefully to handle in clay bricks to avoid wastage.
