To reap the full benefits of AAC/CLC blocks, they need be used in combination with Perlcon Blockbond, light weight mortar. Uniquely formulated to match the strength and be compatible with AAC/CLC blocks.

AAC/CLC blocks are light weight, evenly finished and provide insulation. They have lower compressive strength and absorb much less water in comparison to bricks/CC blocks.

The use of conventional sand cement mortar which is heavier, nullifies the advantages of AAC/CLC blocks. Because of mismatched properties with respect to AAC blocks and because it forms thicker joints, there is always a high probability of crack formation in walls made with AAC blocks and sand cement mortar.

Blockbond forms a thin and even masonry layer and joint. It also reduces possibility of crack formation. It provides better heat insulation and is 2.25 times lighter than conventional mortars along with high coverage.
