Block joining mortar


Trimurti AAC Block Joining Mortar is a ready to mix, selfcuring cementitious mortar for laying of AAC, CLC, Hollow concrete block and bricks.
It's a factory made premixed mortar blended with carefully selected raw materials such as graded sand, mineral binders and ordinary Portland cement (OPC) in combination with selected polymeric additives which help in providing mechanical bond and adhesion between the blocks and block to surface. Designed for use with water to produce high strength thixotropic mortar.

Trimurti Block Joining Mortar manufactured by following strict quality norms and is in compliance with C 1660-09 ASTM standards (, a worldwide standard followed for thin bed mortar for autoclaved aerated concrete masonry that meets the requirements of National and International standards.


High Strength (Tensile Splitting Strength)

Optimally polymerized Trimurti provides additional bond strength apart from the mechanical sandcement bonding due to hydration retainer compounds which gives solid robust wall with long lasting durability.

Flexible & Improved Workability

Due to added polymers it results in improved quality, water retention and open time of mortar.

Coverage (In 30Kg)

1 Cubic Meter Block, with Thickness of 3mm.

Fast Construction and Higher Productivity

Trimurti is a timely setting mortar which allows uninterrupted block mounting which is far lower in time than conventional and ordinary mortars combined with qualities of good workability spread of material and no need of curing Trimurti increases speed of construction - only 24 to 48 hrs required before next stage like plastering.

ASTM Complaint

It is specially formulated and tested to be in compliance with ASTM C 1660-09 and gives the  confidence to the consumer of a product based on researched standards.


No curing required after block work is done, thus saving critical resources like water.

Less Storage Space

Trimurti Block Joining Mortar mix is ready to mix product there by eliminating need for bulk storage of sand and cement.

Construction Accuracy

Due to measured application and thin bed. the wall construction is accurate.

Withstand Hammering and Chiseling

Trimurti are able to withstand the hammering and chiseling required to be done for window, door frames and conducting after 48-72 hours.


  • Pre-wet the blocks and ensure it is touch dry before thin bed block joining masonry is applied.
  • The surface for mounting must be throughly cleaned of all dust, loose materials, oil grease etc.
  • Ensure that surface is at, structurally sound and free from any other contamination which would reduce the bond strength.
  • The surface should be free from voids, holes and cracks.


Gradually add 3 parts of powder to 1 part of water (by volume) Take water in the container and slowly add the powder into water while mixing by hand or slow speed mixing machine.
Mix for 3 to 5 minutes till a smooth thixotropic mix without lumps is obtained, resulting into good bonding strength with the blocks.
