AAC Blocks
Construction
AAC (Autoclaved Aerated Concrete) Blocks are lightweight, strong, and sustainable construction materials designed for faster, energy-efficient, and eco-friendly construction.
Advantages of AAC Blocks
Common Challenges with AAC Blocks
Cracking Issues
Improper installation or stress distribution can lead to cracks.
Moisture Absorption
AAC blocks can absorb moisture if not treated properly.
Brittle Nature
They have lower impact resistance compared to traditional bricks.
High Initial Cost
Initial material costs may be higher than conventional materials.
Plaster Adhesion
Special surface treatment is required for better plaster bonding.
Specialized Installation
AAC blocks require proper installation methods and skilled handling.
Low Tensile Strength
The material has lower tensile capacity than traditional concrete.
Poor Fixing Ability
Fixing heavy objects directly onto AAC blocks can be difficult.
Reduced Mortar &
Plaster Usage
AAC block systems reduce the requirement for mortar and plaster, lowering material consumption.
Lower
Structural Costs
Lightweight construction helps reduce structural load and foundation costs significantly.
FTR Solution System Components
Block Bond
A super polymerized bonding material used for AAC block pasting and pointing. It improves adhesion, shear resistance, and crack prevention while creating monolithic wall behavior.
Key Benefits
- Strong inter-course bonding
- Better shear resistance
- Reduced crack propagation
- Uniform stress distribution
- Improved load transfer performance
ERP Fiber (Polymerized Mortar)
ERP Fiber is applied as a plaster layer over AAC blocks with nylon mesh reinforcement. It helps prevent cracks and strengthens the surface.
Features
- Prevents surface cracking
- Acts as base plaster
- Improves durability
- Supports mesh reinforcement system
ERP Smooth (Elastomeric Paintable Putty)
ERP Smooth provides the final finishing layer for a seamless and paint-ready surface.
Features
- Smooth seamless finish
- Ready for direct painting
- Washable surface
- Available in multiple colours
Preventive Measures
Proper Block Alignment — Ensure all blocks are placed in correct alignment using aluminum leveling tools.
Use of Block Bond — Use thin layers of Block Bond to avoid material overflow and ensure better adhesion.
Void Filling — Fill larger gaps using Block Bond mixed with AAC pebbles.
Proper Electrical Conduit Fixing — Electrical conduits should be fixed using Block Bond for stronger integration.
Corrective Measures for Cracks
Crack Repair Process
- Remove loose particles
- Open cracks properly
- Apply ERP Smooth inside grooves
- Apply nylon mesh reinforcement
- Finish with additional ERP Smooth coats
Surface Protection
Use premium emulsions and anti-fungal coatings to ensure durability and long-lasting finish.
