Foamed mineral building- and structual element, method for its production and apparatus for carrying out said method

摘要

Mineral foam-like building and structured material is based on a uniform expanded alkali silicate and/or ammonium silicate matrix which surrounds an open and/or closed pore structure. An Independent claim is also included for a process for the production of the mineral foam-like building and structured material comprising adjusting the water content of the alkali silicate and/or ammonium silicate starting material to a determined value and foaming the pretreated material.
