摘要
A foaming agent is used for foaming a building material binder paste or a building material slurry for producing porous lightweight-construction and insulating materials. On curing of the foamed slurry, the foam bubbles generate pores in the building material. The foam obtained from the foaming agent is stabilized using a long-chain or medium-chain polycarboxylate ether (PCE). The foaming agent includes 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.
