Product Details
Category: AAC BLOCKS
Product Description
Sand-based AAC blocks use finely ground quartz sand as their primary silica source rather than fly ash. They offer lower drying shrinkage, superior dimensional stability, and high crack resistance, making them ideal for coastal high-rises, long walls, and fine-finish residential towers.
Key Technical Specifications
- Dry Density: 550 – 650 kg/m³ (approx. 3 times lighter than traditional clay bricks)
- Compressive Strength: 3.5 – 5.0 N/mm² (exceeds standard structural and partition needs)
- Fire Resistance: Up to 4 hours of protection
- Thermal Conductivity: 0.13 – 0.16 W/m·K, which helps lower HVAC energy use by 25–30%
- Standard Size: Typically 600 mm × 200 mm with varying thicknesses (100 mm for partitions; 150 mm to 200 mm for external walls)
