AAC Block Joining Mortar
hahne Set AAC is a factory-mixed, polymer-modified thin bed joining mortar specially formulated for laying AAC, ALC, and lightweight concrete blocks. Developed with German formulation technology and enhanced with high-performance additives, it provides superior adhesion, strength, and workability for thin joint applications, ensuring faster, cleaner, and more durable masonry construction.
- Excellent Bond Strength: Ensures a firm grip between AAC blocks, minimizing cracks and joint failures.
- High Coverage: Requires only 3–4 mm joint thickness, reducing material consumption by up to 70% compared to conventional mortar.
- Shrinkage Controlled: Prevents shrinkage cracks due to optimized polymer blend.
- Ready to Use: Just add water and mix; no site blending of cement or sand needed.
- Improved Workability: Smooth, creamy consistency for easy application and better productivity.
- Weather Resistant: Suitable for both internal and external applications.
- Joining of AAC, ALC, Hollow, and Cellular blocks in walls and partitions.
- Ideal for both load-bearing and non-load-bearing structures.
- Suitable for internal and external masonry walls.
