Another example of the versatility of ECKART products: Our leaf-shaped aluminium powders and pastes are used in the construction industry for producing aerated concrete. Porous, or light weight concrete is created by the reaction of aluminium powder in aqueous-alkaline solutions; the concrete mass is thus foamed and innumerable small bubbles or pores formed.
The pores give this type of concrete several extremely useful characteristics: the material is light, yet it has a high degree of hardness. It is easy to handle and is remarkable for its unsurpassed thermal insulation properties. It would be hard to imagine today's low-cost prefabrication method for commercial and private buildings without aerated concrete.
