METHOD OF DESIGNING COMPOSITIONS OF FOAM-CONCRETE MIXTURES Russian patent published in 2015 - IPC C04B38/10 

FIELD: chemistry.

SUBSTANCE: invention relates to production of structural materials, particularly foam-concrete, and can be used at factories producing foam-concrete articles and structures, when producing commercial-grade foam-concrete and in monolithic construction. The method of designing compositions of foam-concrete mixtures includes determining the volume of components of the foam-concrete mixture - cement, aggregate, water and foam - by calculation and determining consumption of the components per 1 m³ of the foam-concrete mixture taking into account packed density (ρ_n) of dry starting materials, concentration of the aqueous solution of the foaming agent, volume of foam with optimum concentration of the aqueous solution of the foaming agent, utilisation factor of foam with optimum concentration of the aqueous solution of the foaming agent (or stability factor of foam with optimum concentration of the aqueous solution of the foaming agent in the cement mortar).

EFFECT: use of the disclosed method of designing composition of foam-concrete mixtures simplifies determination of consumption of all components of the foam-concrete mixture.
