METHOD FOR OBTAINING A FOAM CONCRETE MIXTURE Russian patent published in 2022 - IPC C04B38/10 C04B40/00 B28C5/38 

FIELD: construction materials.

SUBSTANCE: invention relates to the production of foam concrete used in the construction and repair of residential, industrial buildings and structures where continuous supply of foam concrete mixture is required. The method for obtaining a foam concrete mixture includes mixing in a given ratio of cement with water, filler: sand fractions less than or equal to 0.315 mm and/or a reinforcing additive: microfiber in a mixer-activator with a rotation speed of 200-500 rpm with heating of the mixture to 30 - 45 degrees Celsius and hydro-activation of cement at a water-cement ratio from 0.28 to 034, preparation of the foaming agent by stirring for one minute in a container of protein foaming agent concentrate with water in a ratio from 1:50 to 1:25, followed by aeration of the resulting foaming agent solution with compressed air at a pressure of 0.5 - 0.6 MPa in a foam generator until foam is formed with a multiplicity of 20 - 40, obtaining a foam concrete mixture at the place of application of foam concrete by mixing in a mixer-porizer with a rotation speed of working bodies 100 - 500 rpm in a given ratio of the specified activated cement mixture and the resulting foaming agent solution.

EFFECT: development of a method that provides continuous production of foam concrete mixture directly at the construction site without loss of quality of the foam concrete mixture.
