AAC blocks are a precast, foam concrete, sustainable construction material made from aggregates of quartz sand, calcined gypsum, lime, portland cement, water and aluminium powder. After mixing and moulding, the concrete is autoclaved under heat and pressure and it thus gains its distinctive properties. AAC bricks are in high demand, owing to their high strength, load-bearing and thermal insulation properties.
High compressive strength: The average compressive strength of the block is 3 to 5 N/mm2. Thus, it is much stronger and better than bricks of the same density.
Pest-resistant: AAC blocks are prepared from inorganic materials, which help in protecting the structure from pests such as termites, rodents, etc.
Soundproof: The lightweight and porous structure of AAC blocks enables high sound reduction. For this reason, the material is widely used in the construction of studios, hotels, hospitals, etc.
Moisture-proof: Moisture can severely damage a structure. The macro-pores inside AAC blocks ensure low absorption of water. Thus, they provide better moisture protection.
