Who We Are

NCL AAC Blocks

Recently, Alltek Division has introduced NCL AAC Blocks. NCL Blocks (lightweight fly-ash bricks) are manufactured in a state of the art Autoclave Aerated Technology

* Light Weight  * Echo-Friendly  * Consistent Quality 

* Good Insulation from Heat & Sound  * Made of Nagarjuna Cement 

NCL AAC Blocks

SAVINGS

  • On joint & plastering mortars
  • On steel by 20 – 25% & concrete by 10%
  • On labour & transportation cost
  • On project implementation time

Dry - Mix Mortors

  • Factory produced cement based, pre-mixed motors with high quality polymers & additives.
  • only water need to added at site.
  • No need to procure/store individual materials like sand, cement etc.
  • Facilitates more productivity with reduced labour.

NCL Render 608

  • NCL Render 608 is used for plastering walls and ceiling.
  • NCL render is mixed @ applied using spray machine.
  • This will speedup the plastering work and reduced labour cost.
  • Also Economical as thickness can be reduced to 10 to 12 mm with smooth finish
  • For manual application using traditional tools use ncl render 608-HP.

Preparation Procedure

(1) Wash or pre-wet the Blocks to remove dust particles.

(2) Take 175 ml clean water per kg of ncl masonry glue 110 in a deep tub.

(3) While using electric drill with a whisk, add ncl masonry glue slowly and continue mixing for 3 min.

(4) Allow the mixer to stand for five min and remix again. Add required additional water to get uniform paste and remix.

(5) Uniform bed is made before fixing the block for even surface contact.

(6) Blocks are to be laid uniformly and complete the wall.
