Aluminium Powders for Autoclaved Aerated Concrete Blocks (AAC)
Product Information:
Coarse grade of flake aluminium powder is non-ignitable and with controlled fatty acid content. It reacts with phosphorous in the production of aluminium phosphide (used as fumigant in the grain storage godowns).
NOTE:
Wet sieving with mineral spirit as rinsing liquid.

Product Information:
Milled flake aluminium powder is specially produced for adding into the aqueous
alkaline slurry to evolve hydrogen gas bubbles in the making of light weight
AAC Blocks. Di erent grades of powders are processed with speci c attention
to the size of bubbles formed and rate of evolution of gas to suit individual
customer’s requirement.
NOTE:
Wet sieving with mineral spirit as rinsing liquid.
