ABSTRACT:
A process for the production of a shaped article from a lightweight-aggregate granulate and an inorganic binder has the following process steps:provision of a viscous binder that has been prepared on the basis of diatomite and caustic soda or caustic potash solution,mixing of the binder with lightweight-aggregate granulate,shaping of the lightweight-aggregate granulate binder mixture, andthermal exposure of the lightweight-aggregate granulate binder mixture under foaming and bonding of the lightweight-aggregate granulate particles in a foamed binder matrix to create the shaped article.
