Finest TALCRETE® gas-forming grade — 94% Min metallic aluminium for AAC block production.
Milled flake aluminium powder is specially produced for addition to an aqueous alkaline slurry, where it reacts to generate hydrogen gas bubbles during the manufacture of lightweight AAC blocks. The different grades of aluminium powder are processed with specific attention to particle size, bubble formation, and the rate of gas evolution to meet individual customers' requirements.
