Performance Parameter of Aluminum Powder for AAC
Aluminum Powder for AAC is manufactured through advanced dry grinding technology. It features high active aluminum content, fast gas generation speed, easy dispersion and long storage stability. The particle size distribution can also be adjusted according to different AAC production formulas and density requirements.
This product is widely used in autoclaved aerated concrete (AAC), lightweight concrete blocks and prefabricated construction materials. During the production process, the aluminum powder reacts with alkaline substances to release hydrogen gas, forming a uniform porous structure inside the concrete.
High active aluminum content
Fast and stable gas generation
Excellent dispersion performance
Uniform particle size distribution
Stable reaction efficiency
Long storage life
Suitable for different AAC formulas
Consistent pore formation performance
Used in autoclaved aerated concrete blocks to generate fine and uniform air pores, reducing concrete density while maintaining strength.
Suitable for lightweight wall panels, insulation blocks and construction materials requiring reduced weight and thermal insulation.
Widely applied in prefabricated concrete products for modern construction industries.
In AAC manufacturing, aluminum powder reacts with calcium hydroxide and water in an alkaline environment, releasing hydrogen gas that forms millions of tiny pores inside the concrete slurry.
The gas generation reaction directly affects:
Density of AAC blocks
Pore uniformity
Compressive strength
Thermal insulation performance
Production stability
Therefore, selecting the correct aluminum powder grade is very important for AAC manufacturers.
