Product type
AAC blocks, or Autoclaved Aerated Concrete blocks, are lightweight precast building materials made from a mixture of cement, lime, water, and aluminum powder. This unique composition results in a porous structure that provides excellent insulation properties and fire resistance. AAC blocks are typically used in the construction of walls, partitions, and other structural elements in residential, commercial, and industrial buildings.
| Material | Cement, lime, water, and aluminum powder |
| Density | 400 to 800 kg/m³ |
| Thermal conductivity | 0.09 to 0.16 W/mK |
| Compressive strength | 3 to 6 MPa |
| Standard sizes | 600 x 200 x 100 mm to 600 x 200 x 300 mm |
| Fire resistance rating | Up to 4 hours |
When selecting AAC blocks, consider factors such as density, compressive strength, and thermal conductivity to ensure they meet your project's requirements. Specify the desired sizes and any particular fire resistance ratings needed. Additionally, inquire about certifications and standards compliance relevant to your region, as well as the quantities required for your project to receive an accurate quote.
