FIELD: methods for preparation of concrete mix with additives of superplasticizers. SUBSTANCE: method for preparation of concrete mix consists in that cement is preliminarily treated with superplasticizer in the amount of 2.2-20% of cement mass by mechanical treatment with use of 30-120 W per kilogram of treated mass for 20-3.104 s, and produced binder is mixed with added water. Depth of concrete carbonization amounts to 3.0-3.5 mm. EFFECT: higher strength, reduced carbonization with preserved mobility of concrete mix. 2 tbl
