Plasters and Mortars
Technical aluminium flakes, aluminium powders,aluminium paste, foil grit, spray grit
Further applications concerning foaming of masses, based on different cementitious materials, with aluminium powders and pastes include adjusting the effect of expansion in insulation plasters and restoration plasters and for shrinkage compensation in mortars, screeds and sealing compounds.
Insulation plasters and restoration plasters, mortar and sealing compounds can be made porous based on the same principle as for autoclaved aerated concrete. On one hand, adding aluminium improves processing qualities, and on the other, the pore formation compensates for the shrinkage that occurs during the hardening process.
Usually mixtures of aluminium powders and calcium carbonate powders are used to avoid the risk of explosion when dealing with aluminium powders when processing dry mixtures.
