AAC blocks

NCL – AAC Blocks

Building walls for strength and comfort

The lightweight NCL AAC Blocks are made of lightweight fillers, cement, fine additives, lime, etc. Through a chemical reaction that creates a consistent cellular structure. These AAC Blocks are then cured in an autoclave under high-pressure steam, which strengthens them.

Effective soundproofing & insulation.

High structural strength.

Swift construction with lightweight materials.

Certified green and fire-resistant.

Unbeatable advantages, that set us apart!

NCL AAC Blocks

Before application – wet the brick. For better performance use self curing block / Brick mortar with 3 to 4 mm thickness and apply the same with notching trowel. Apply a thin layer of block mortar in the thickness of 3 to 4 mm on the clean and leveled surface using proper trowel on which the block work is to be carried out. Place the block on the laid block mortar in proper line and level. After placing the first block apply the jointing mortar of the same thickness i.e. 3-4 mm on both horizontal and vertical joint of the block then place the AAC bricks. The lentil should be placed for every 5 to 6 layers of AAC Blocks or 6 m length to avoid cracks. It should be placed on a complete block. Use a tool like hacksaw or rotary cutter to cut into required size & shape. Curing is not required.
  1. The level from base to the top layer should be properly horizontal.
  2. There should not be any gap between the joints of AAC Blocks.
  3. Bottom layer of AAC Block should be properly laid, so that no gaps should come in between otherwise the blocks would crack.
  4. The lentil should be placed after every 5 to 6 layers of AAC Blocks or 6 m length to avoid cracks. It should be placed on a complete block.
  5. Storage on dry and even surface to avoid damage and contact with moisture.
  6. Before application – wet the block.
  7. Use self curing block mortar with 3 to 4 mm thickness only and notching is mandatory.
  8. Use a tool like hacksaw or rotary cutter.
  9. Should rest on full block.
  1. Do not use a rich mortar mix as it tends to shrink & might crack.
  2. Do not flood the brick with water.
  3. Do not construct a wall without coping the beam.
  4. Do not stack the blocks in haphazard manner or leave them exposed to rain or moisture
  5. Do not use tools like hammer, chisel etc. to cut the block
