Product type
Lightweight AAC blocks, or Autoclaved Aerated Concrete blocks, are precast building materials made from a mixture of cement, lime, water, and a foaming agent. This unique composition results in a lightweight yet durable product that offers excellent thermal insulation and fire resistance. The blocks are manufactured through a process of autoclaving, which enhances their strength and stability.
| Density | 400 to 800 kg/m³ |
| Thermal conductivity | 0.09 to 0.16 W/m·K |
| Compressive strength | 3 to 7 N/mm² |
| Standard sizes | 600 x 200 x 100 mm to 600 x 200 x 300 mm |
| Fire rating | Up to 4 hours |
When selecting lightweight AAC blocks, consider the density and compressive strength required for your specific application. It's important to specify the desired thermal insulation properties and fire resistance ratings. Additionally, inquire about available sizes and whether custom dimensions are possible. Certifications for environmental standards or quality assurance may also be relevant, depending on your project requirements.
