FOAMING AGENT AND METHOD FOR THE FOAMING AND STABILIZING OF A BUILDING MATERIAL SLURRY FOR POROUS LIGHTWEIGHT BUILDING MATERIALS
The foaming agent is used for foaming a building material binder paste or a building material slurry for producing pory lightweight-construction and insulating materials. On curing of the foamed slurry, the foam bubbles generate pores in the building material. In accordance with the invention, the foam obtained from the foaming agent is stabilized using a long-chain or medium-chain polycarboxylate ether (PCE). The foaming agent consists of a foam-forming ionic surfactant component, at least one fatty alcohol and at least one PCE in an aqueous-organic solvent which is selected from the group of alkyl glycols, alkylene glycols up to C6 alkyl, diglycols and diglycol ethers, and also, optionally, up to a maximum of 20 wt%, based on the mixture, of further ingredients. Additionally specified are methods for producing a pory lightweight-construction and insulating material by means of the binder paste foam or the foamed building material slurry, and also associated porous lightweight construction products.
