COMPOSITION FOR MAKING FOAMED GYPSUM ARTICLES Russian patent published in 2012 - IPC C04B38/10 C04B38/02

Abstract RU 2461532 C1

FIELD: chemistry.

SUBSTANCE: invention relates to production of construction materials, particularly foamed gypsum compositions used to make light heat-insulating materials with a porous structure. The composition for making foamed gypsum articles contains the following in wt %: gypsum plaster 29.0, phosphogypsum 29.0, nonionic surfactant OP-7 0.01, tartaric acid 0.1, iron sulphate 0.003, 25% aqueous hydrogen peroxide solution 0.01, dimethylvinylethynylcarbinol 0.001, water - the balance.

EFFECT: gypsum-based foamed material, having high strength, low specific weight, high heat-insulating and frost-resistance properties.
