FIELD: construction.
SUBSTANCE: manufacturing method of a complex nanodisperse additive for high-strength concrete consists in production of a suspension with solid phase concentration of 3% by ultrasonic dispersion at ultrasound frequency of 35 kHz. With that, the suspension contains 65-70 wt % of a mineral component - metakaolin, 30-35 wt % of C-3 superplasticising agent in the form of a dry substance and water.
EFFECT: reduction of particle sizes; reduction of time for ultrasonic action and simplification of an additive production technology.
