FIELD: chemistry.
SUBSTANCE: invention relates to preparation of a powdered complex additive for concrete mixture and can be used in the construction materials industry. The method of preparing the powdered complex additive for concrete mixture involves mixing in a cyclic action mixer for 3-5 minutes 12-14 wt % plasticiser and 86-88 wt % mineral carrier, followed by grinding in an activator with a vertical working chamber with rotor speed of not less than 10000 rpm until a powdered complex additive with particle size 0.5-100 mcm is obtained.
EFFECT: improved plasticising properties of said additive.
