FIELD: construction.
SUBSTANCE: in method to make a concrete mix the following components are mixed for 50-60 s: 5-10 wt % of the total cement amount and 20-35 wt % of the total amount of mixing water with 0.5-0.75% of total mass of superplasticiser cement and 8-12 wt % of the total mass of microsilica cement. Afterwards during mixing for 50-60 s fine and coarse fillers are added, and then in turns the remaining parts of cement and mixing water, and final mixing is carried out for 50-60 s.
EFFECT: simplification of method.
