Characteristics of aerated lightweight concrete blocks

Standard Block Size




Standard sizes of aerated blocks & quantity per Cubic Meter
Width x Height x Length (in MM)
100 x 200 x 600 = 83 Pcs.
150 x 200 x 600 = 55 Pcs.
200 x 200 x 600 = 41 Pcs.
Qty




What is Cubic Meter? Concrete is measured by volume. & Measurement unit is CUBIC METER (M³)
Volume of 1Meter x 1Meter x 1Meter is 1 Cubic Meter
Wall




How many aerated blocks required to construct a wall?
75 Blocks are required to build a wall of 100 SqFt
Thickness of wall = Thickness of block
Characteristics of blocks : Steam Curing - AAC Natural Curing - ALC/NAAC

Compressive strength and water absorption percentage are related to density.

Advantages of Aerated Lightweight Concrete Bricks - AAC and ALC/NAAC

  • Reduction of steel & cement requirement in structure due to less weight of wall results in savings up to 15% of total project cost.
  • Facilitates construction of unplanned walls anywhere & anytime.
  • Weighing approx ⅓ rd than clay or fly ash bricks and blocks have an average compressive strength >2.5 N/mm2

  • Thermal insulation performance is far better than clay bricks & RCC
  • With a just 100 mm thickness of wall 700 Kg/M3, aerated lightweight concrete Bricks offers fire endurance for heat transmission for Long hours.

  • Water absorption of aerated lightweight brick is relatively lower compared to conventional bricks. It is < 25 % for a density of 700 kg/m3.
  • Closed cell structure of aerated lightweight concrete bricks reduces water absorption, So, no more damp spots on the wall.
  • Lower water absorption property of these blocks will help to reduce cracks in walls
  • The lightness of the material increases resistance against earthquakes

  • Due to cellular structure, it gives better sound insulation
  • It is ideal for any construction like houses, apartments, commercial constructions, schools, hospitals and amphitheaters. Etc.

  • Less electricity required for AC/Heater Due to Good thermal Insulation Property
  • Least energy requirement on production

  • Aerated lightweight concrete bricks are manufactured with fly ash - 100% recycled resource
  • Valuable soil is not consumed
  • Very less energy is used for manufacturing

  • Compressive strength increases with age of ALC/NAAC Blocks
  • Typical Life is approximately double than clay bricks

  • Due to less weight & larger size its economical in transportation and handling
  • Significant reduction of overall weight results in savings on structural frames, footings or piles (steel and cement).
  • Lesser joints and accurate dimensions of blocks, reduces mortar, plastering and precious time of labor resulting in huge savings
  • The bricks can be sawed, drilled and shaped like wood using standard hand tools, regular screws and nails. It is simpler than brick or concrete. so less wastage
  • By using a 6 inch block in place of 9 inch brick, customers get an additional 2% - 3% carpet area. This savings on account of additional carpet area gained is more than cost of bricks
  • Savings in overall construction cost can be up to 15% when using aerated lightweight concrete blocks, as compared to clay bricks after considering the resulting savings in steel, structure, cement, sand, gravel and time etc
