Why AAC Blocks are Popular in tropical climates
Autoclaved Aerated Concrete (AAC) blocks have rapidly gained popularity in tropical climates due to their light weight, thermal insulation properties, and earthquake resistance. Cities like the region, the region, the region, and the region have seen a surge in AAC block construction over the past decade.
The Problem with Using Regular Cement Mortar for AAC Blocks
Many contractors still use conventional 1:6 cement-sand mortar for AAC block laying — with joints of 12–15 mm thickness. This is incorrect and leads to several problems:
- Thick joints create thermal bridges, reducing the insulation value of AAC blocks
- Excessive water in thick mortar is absorbed by AAC blocks, causing shrinkage cracks
- Higher material cost and slower construction speed
- Weak joints compared to proper block mortar
