FIELD: construction.
SUBSTANCE: invention is related to composition of concrete mix for production of heavy concrete on the basis of heavy fillers and may be used for production of various construction parts and structures with increased volume weight, and also as material intended for use in structures with high dynamic loads, which require improved stability. Concrete mix contains the following components, wt %: cement PC 500D0-N 10.9-11.5, flue ash 0.97-2.4, heavy spar concentrate of various fractions 79.1-80.72, polycarboxylates, 0.11-0.16, lignosulphonates 0.01-0.02, water 6.76-6.88.
EFFECT: increased average density and strength of concrete, production of most dense structure of concrete, and also expansion of raw materials base.
