FAQS

Autoclaved aerated concrete (AAC) Block is a lightweight, precast building product used around the world as a superior substitute for traditional clay bricks and is available in blocks and panels of various sizes. AAC Block is an ideal material for structural walls, firewalls, sound walls, and floor and roof systems.

AAC Blocks and panels with a minimum of 8" thickness are suitable for load-bearing applications, when used in accordance with our published design aids and allowable stress listings. 6'' blocks may be used for some interior load bearing applications. Load bearing applications require vertical cores reinforced with rebar and concrete. Code requires cores at corners, doors and windows. For design information, please consult our Technical Manual, or contact us to request a technical manual.

Traditional sand cement mortar made at site can be used but it is advisable to use Thin-bed mortar designed especially for AAC Blocks. It is delivered in ready-to-mix powder form. It is polymer modified Portland cement specifically designed to retain water from entering the pores of AAC blocks, which perfectly bond AAC blocks. Just 2-3 mm thin mortar bed is needed to adhere the blocks. This is extremely thin joint which also prevents heat loss and speeds installation.

Many of the conventional exterior finishing system such as one coat plastering and two coat systems can be used over AAC Blocks as an exterior finish. Other options such as stucco, acrylic finishes, brick, stone, siding, or approved paints can also be used. On the inside of the building, AAC Block may be directly finished with Gypsum boards sheetrock, plaster, stucco, wood panel or tiles.

Yes, AAC Blocks are extremely safe and time tested, they are being used in construction since 1923 in Europe and in India they are being used since 1972, moreover AAC Blocks are probably the safest building product available. Tests conducted by independent laboratories shows that AAC is not hazardous or toxic. It doesn't emit fumes or emit radiation above that of familiar food. There is no waste produced during manufacturing as well it neither contains nor emits toxic substances.

AAC Blocks are 9 times the size of traditional bricks. These results in substantial saving in cement due to fewer joints compared to brickwork and finished plasterwork, more over AAC blocks are factory finished with precise edges and shapes. This results in consumption of substantially less plaster, POP, or Putty finish, which reduces walling cost in AAC blocks. Due to lightweight and low density, over all dead load reduces, thus there is saving structural steel consumption compared to conventional clay masonry. There is increase in carpet area as well by 3% to 5% as well depending on design. As the blocks are lighter in weight and size is also bigger the construction speed is higher and there is also saving in operating cost which is realized through reduction in maintenance, energy bills and insurance.

It is depend on size of block. For example only 42(approx) block require in a cubic meter if size of block is 600*200*200 mm.

Cement,sand, Fly ash, Lime and aluminium powder are the key ingredients for making ultralyte AAC blocks. They are cured under steam curing known as Autoclave. Due to sustainable material envelope, these products are certified under green rating system and helps builder to get credit points.

Yes, they can be easily cut/saw to the desired size.

Only one coat plastering is required over blocks as exterior finish. Thus here the two coat plaster required for clay bricks is avoided leading to cost & time savings. For interior finishing of the walls, Putty can directly be applied & is sufficient to give you supreme finishing.

Ultralyte AAC blocks provide excellent acoustic property leading to better sound absorption. There by making the blocks a hot product for constructing hotels & Airport buildings. The famous Dubai International Airport is a perfect example of acoustic properties of a building made through AAC Blocks.

Ultarlyte AAC Blocks have high fire resistance rating of at least 4 hrs and more.

Ultarlyte AAC blocks reduce the dead load significantly and also ensures saving in steel & concrete. It requires lesser number of joints, which results in saving of jointing material, time and labor.

550-650kg/m3 and 650-750kg/m3

AAC Blocks are bigger than the size of traditional bricks. These results in substantial saving in cement due to fewer joints compared to brickwork and finished plasterwork, more over AAC blocks are factory finished with precise edges and shapes. This results in consumption of substantially less plaster, POP, or Putty finish, which reduces walling cost in AAC blocks. The density of AAC Blocks is one-third the density of Clay bricks thus it reduces the dead load of the building significantly. Due to this there is saving in structural steel consumption compared to conventional clay masonry. There is increase in carpet area as well. As the blocks are lighter in weight and size is also bigger the construction speed is higher so there is huge saving in operating & construction costs.
