The amount of aluminium powder and aluminium paste used in making autoclaved aerated concrete is low, but every chain is only as strong as its weakest link. With nearly 100 years of experience as a producer of metal powders, our ambition is to make Benda-Lutz a strong link in this chain.
Mortar, plaster and flooring that are based on cement lose volume as they harden. This loss is responsible for undesirable cracking, which diminishes quality and function. These problems can be eliminated by the addition of Benda-Lutz® Expandal.
