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.

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.
