How much does a AAC block cost?
AAC blocks: Sizes and prices Manufacturers of autoclaved aerated concrete produce AAC blocks ranging in varied sizes and strengths. The price of rectangular AAC blocks size (length X height X weight) of 600mm x 200mm x 250mm can range between Rs 2,000 and Rs 3,500 per cubic meter.
Are autoclaved aerated concrete blocks (AAC blocks) safe?
Among the innovative construction materials used across the world, autoclaved aerated concrete blocks (AAC blocks) are considered superior to other conventional materials like burnt clay bricks that cause environmental hazards.
How high can you build with AAC blockwork?
Although it is one-fifth the density of normal concrete it still has half the bearing strength, and loadbearing structures up to three storeys high can be safely erected with AAC blockwork. Increasingly, AAC is being used in Australia in its panel form as a cladding system rather than as a loadbearing wall.
Can AAC wall panels be used as blockwork?
External AAC wall panels — which are not blockwork but are precast units — can provide loadbearing support in houses up to two storeys high. AAC panels and lintels contain integral steel reinforcement to ensure structural adequacy during installation and design life (see Construction systems).
What are the characteristics of AAC blocks?
The AAC blocks are energy efficient, durable, less dense, and lightweight. It is manufactured by adding a foaming additive to concrete in different sizes of molds as per requirement, then wire-cutting these blocks or panels from the resulting ‘cake lump’ and ‘heating them with steam. This process is called as Autoclaving.
Why can’t AAC be used as a building material alone?
The brittle nature of the blocks requires longer, thinner screws when fitting cabinets and wall hangings and wood-suitable drill bits or hammering in. Insulation requirements in newer building codes of northern European countries would require very thick walls when using AAC alone.
