NCL AAC BLOCKS
PRODUCT DESCRIPTION
The light weight NCL AAC BRICKS are made of light weight fillers, cement, fine additives, lime etc.
through chemical reaction which creates constant cellular structure and cures in autoclave under
high pressure stream which strengthens the bricks.
ADVANTAGES
- Best suitable alternative for Clay Bricks / Hollow / Solid Concrete Blocks
- Light weight bricks reduce the dead load on structure
- Speedy work
- Dimensional accuracy
- Can be cut into any size / shape easily
- Very good mechanical strengths
- Energy efficiency
- Fire-resistant
- Sound insulation
- No fungal growth
- Better wall surface level
- No VOC
- Eco-friendly
- Conforms to IS 2185
SAVINGS ON OVERALL PROJECT COST
- On jointing and plastering mortars
- On steel by 20-25% and concrete by 10%
- On labor and transportation cost
- On project implementation time
Workability:
- Easy to lay
- Can be cut in to any size/shape
INSULATION
- Superior thermal insulation that reduces load on air-conditioner
- Superior sound insulation with a STC rating of 44

Installation: 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.
DO'S
- The level from base to the top layer should be properly horizontal
- There should not be any gap between the joints of AAC Blocks
- Bottom layer of AAC Block should be properly laid, so that no gaps should come in between otherwise the blocks would crack
- 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
- Storage on dry and even surface to avoid damage and contact with moisture
- Before application – wet the block
- Use self curing block mortar with 3 to 4 mm thickness only and notching is mandatory
- Use a tool like hacksaw or rotary cutter
- Should rest on full block
DON'TS
- Do not use a rich mortar mix as it tends to shrink & might crack
- Do not flood the brick with water
- Do not construct a wall without coping the beam
- Do not stack the blocks in haphazard manner or leave them exposed to rain or moisture
- Do not use tools like hammer, chisel etc. to cut the block
