Formulation for the preparation of a Tonleichtmaterials, method for producing a Tonleichtmaterials, Tonleichtmaterial and methods for manufacture of brick modules using the Tonleichtmaterials

The present invention relates to a formulation and a method for producing a Tonleichtmaterials which is stabilized for further use in the presence of aqueous media by a hydrophobizing agent. Furthermore, the invention relates to a process for the manufacture of brick modules from clay materials, said Tonleichtmaterial the one is added as an additive to reduce the bulk density and to improve the insulation properties and the other pore-forming agents is used as added to the better the combustion process controllable and to make fewer emissions.
