Another example of the versatility of ECKART products: Our leaf-shaped aluminum powders and pastes are used in the construction industry for producing aerated concrete.

Porous, or light weight concrete is created by the reaction of aluminum 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.
