FIELD: construction.
SUBSTANCE: method for production of water-cement mix includes mixing cement with water and ultrasonic treatment of produced mix with field with intensity of (7÷70)104 W/m2 at excessive pressure. Plant for realisation of this method includes reservoir to mix cement and water, ultrasonic generator with specified intensity of field and pump installed between them.
EFFECT: improved strength and rate of its increase, density, water impermeability, frost resistance of concrete produced with application of water-cement mix.
