  • FOAMED MINERAL BINDER COMPOSITIONS
    Publication number: 20240336535
    Abstract: A method for producing a foamed mineral binder composition includes the steps of: a) separately providing: (i) an aqueous foam; and (ii) an aqueous slurry including a mineral binder and a dispersed polymer; (b) mixing the slurry of the mineral binder with the aqueous foam to obtain the foamed mineral binder composition; whereby during the production of the foamed mineral binder composition, carbon dioxide and/or a carbonate is provided such that it is incorporated in the foamed mineral binder composition.
