General Instruction For Using MAXCRETE AAC Blocks


Unload blocks on a dry level surface raised above ground and cover them to prevent exposure to rain or severe weather conditions.

Mortar ratio

The ideal mortar mix ratio of cement and sand is 1: 4.

Joint thickness

Mortar joint thickness should be 8-12 mm.

Curing of Masonry Wall

No need of Curing except for mortar joint

Plaster Thickness

Plastering thickness should be 10 mm for internal walls and external plaster should be 12-15mm.

Coping Beam

For AAC blocks, it is recommended to provision bond beams after every 1.5-2 meter with reinforcement. RCC Bond beam of thickness 75 mm with two nos of 8 mm dia. rods and 6mm stirrups at 200 mm c/c.


Maxcrete AAC blocks can be easily cut, nailed, drilled, grooved by using ordinary hand tools.

Wall Installation

1st Level Coursing:

  • Place a full width ½’’ deep sand-cement mortar joint using a masonry trowel. Mortar composition can either be 1:4 or 1:5 or any approved thin bed mortar.
  • Set the first corner in the sand-cement mortar
  • Increase or decrease the height of the block by tapping on the block with a rubber mallet or by additional mortar under the block.

Repeat for Additional Corners

Normal Course:

  • Clean the bed joint surface with a brush ensuring there’s no dust or any other particles so that the adhesion with mortar is optimum.
  • Now apply the mortar to head and bed joints using a clean notched trowel. Ensure that the mortar covers the full widths of the joints.
  • Carefully ensure each block is close to the head joint.
  • Finally tap the end of the blocks with a rubber mallet ensuring full surface coverage of the thin bed mortar.
  • Repeat the above steps till the wall is complete.
