A method for the production of foamed concrete and the use of the method

摘要

A method for the production of foamed concrete with a dry density of less than 400 kg / m³ comprising the steps ofa. the formation of a pu adhesives) consisting of cement, water, a network means, wherein a mixture of negatively charged inorganic substances and organic substances with amide groups with corresponding counterions (cations), the two or trivalent cations or a mixture thereof, and / or an organic compound having excess positive charges from the class of cationic surfactants and / or of the quaternary ammonium compounds, and, if appropriate, at least one additive, by mixing the components in a mixer (1),example, formation of a foam consisting of water, air and a foaming agent protein-based of nonpolar and polar amino acids by means of a foam generator (2), wherein said foaming agent is a protein, which is applied to 50 to 80 mass -% of the amino acids a (alanine), e (glutamic acid), g (glycine), i (isoleucine), l (leucine), m (methionine), p (proline), q (glutamine) and v (valine), with a molecular weight between 20000 and..
