FIELD: chemistry.
SUBSTANCE: invention relates to a slurry containing gypsum, foam and ketone resin, wherein the ketone resin is a condensation product of cyclohexanone/formaldehyde/sulfite, and the gypsum includes clay, the ketone resin being selected from sizes with molecular weight of 10,000 to 50,000 g/mol. Invention also relates to a method of manufacturing a lightweight gypsum board with enhanced compressive strength by adding dispersants and to wall boards made using a gypsum-based composition containing said ketone resin as a dispersant and a foaming agent. Invention is developed in dependent claims of the invention.
EFFECT: technical result is improved efficiency of the method of manufacturing lightweight and high-strength plasterboards.
