METHOD FOR MANUFACTURING CONCRETE PRODUCTS Russian patent published in 2023 - IPC C04B41/50 C04B28/04 C04B40/02 

FIELD: construction materials.

SUBSTANCE: invention relates to building materials and can be used for the manufacture of concrete products in civil and industrial construction. The method for manufacturing concrete products includes molding of the product, impregnation of the product at a temperature of 20-30°C in a sol solution of iron (III) hydroxide Fe(OH)₃ with a concentration of C = 3% for 36 hours, followed by hardening of the product, after hardening the product is placed in a constant magnetic field with an internal coercive force of 955 kA/m and a magnetic energy of 287 kJ.

EFFECT: increase in compressive and bending strength at the age of 28 days and an increase in impact strength.
