FIELD: building materials.
SUBSTANCE: group of inventions relates to the field of building materials, namely to a method for the production of inorganic foam based on calcium sulfoaluminate, to porous material based on calcium sulfoaluminate, obtained as a result of curing of inorganic foam, to a composition for manufacture of a composition of inorganic foam based on calcium sulfoaluminate, and to their use. The method for the production of inorganic foam includes mixing of at least one group of inorganic particles – CaCO3; at least one amphiphilic compound with at least one polar head group selected from gallates and carboxylic acids, and with at least one non-polar tail group selected from an aliphatic group containing from 2 to 8 carbon atoms; at least one mixture of inorganic binders, containing at least one mixture of calcium sulfoaluminate and water; foaming of the resulting composition of foam by means of chemical, physical, or mechanical foaming.
EFFECT: obtainment of inorganic foam with closed pores with improved properties, which show heat-conductivity satisfying requirements in combination with a high compressive strength limit, with low density in a dry state.
