Thin Bed Mortar
Hebel RAAC Thin Mortar is a precision-engineered, pre-mixed, high-performance adhesive designed for seamless installation of RAAC units.
Compressive and Adhesive Strength
High-quality AAC thin bed mortars achieve compressive strengths between 5–7 MPa and adhesive bond strengths above 0.3 MPa, ensuring a stable and crack-resistant joint. The thin joint layer (typically 2–3 mm) minimizes thermal bridging and enhances structural uniformity across masonry units.
Workability and Application
The mortar’s fine consistency provides excellent workability and easy trowel application. Its extended open time and quick setting properties allow faster construction cycles while maintaining alignment accuracy. Pre-mixed and ready to use with water, it eliminates on-site mixing variations and reduces wastage.
Thermal and Acoustic Compatibility
Thin Mortar mortars are engineered to match AAC’s thermal expansion characteristics, ensuring uniform behavior under temperature fluctuations. This compatibility helps prevent cracking and improves the overall thermal insulation and soundproofing performance of AAC walls.
Water Retention and Durability
Optimized water-retaining agents ensure adequate hydration and bond development, even under hot or Thin site conditions. The result is improved curing, reduced shrinkage, and superior long-term durability, especially in high-moisture or coastal environments.
Eco-Efficiency and Quality Control
Manufactured in controlled environments, AAC thin mix mortars maintain consistent quality and chemical balance. With low embodied energy and minimal on-site waste, they contribute to sustainable, eco-friendly building practices aligned with LEED and green construction standards.
