Revolutionary Building Technology
Developed in Sweden in the 1920s and perfected over decades, AAC combines concrete’s strength with insulation properties that surpass traditional materials.
Used extensively across Europe, Asia, and the Middle East, AAC is transforming construction worldwide.

How AAC Is Manufactured
Mixing
Raw materials combined with water
Expansion
Aluminum creates hydrogen gas bubbles
Cutting
Wire-cut to precise dimensions (±1mm)
Autoclaving
12 hours at 374°F and 12 bar pressure
Result: Tobermorite crystal formation for strength
AAC Technical Properties
