Latest Patents
Armin Just holds a patent for "Air-curing expanded concrete composed of binder-containing mixtures." This invention relates to an expanded concrete that includes binder-containing mixtures, primarily using Portland cement as specified in DIN EN 197. The concrete is designed to have a water fraction of 20-60% by mass based on the mass of the binder. It also incorporates a chemical gas-forming agent, preferably aluminum powder, at a concentration of 0.05-0.25% by mass. This innovative approach allows for the formation of air pores in the concrete, resulting in a compressive strength of up to 30 N/mm² after curing. The expanded concrete is air-curing at atmospheric pressure under normal ambient temperature, which enhances its usability in various construction applications.
