Product type
Autoclaved Aerated Concrete (AAC) Blocks are lightweight, precast building materials made from a mixture of cement, lime, water, and an expanding agent. This mixture undergoes a curing process in an autoclave, which gives the blocks their unique cellular structure, resulting in low density and high insulation properties. AAC blocks are typically used in construction for walls, floors, and roofs, providing an energy-efficient alternative to traditional masonry.
| Density | 400 to 800 kg/m³ |
| Compressive Strength | 3 to 7 N/mm² |
| Thermal Conductivity | 0.09 to 0.16 W/mK |
| Fire Resistance | Up to 4 hours |
| Sizes | 600 x 200 x 100 mm to 600 x 200 x 300 mm |
| Water Absorption | Less than 10% by weight |
When choosing Autoclaved Aerated Concrete Blocks, consider factors such as density, compressive strength, and thermal conductivity to match your project requirements. Specify the desired sizes and any necessary certifications for fire resistance or environmental standards. It's also important to discuss quantities to ensure availability and pricing.
