FIELD: building materials industry.
SUBSTANCE: invention for manufacturing of concrete products in civil and industrial construction, including production of hydraulic structures. The raw material mixture for high-strength concrete includes, in wt.%: Portland cement CEM II/A-P 42.5 N CC 11.97-12.03, grey sea sand of fraction 1.5-2 mm 28.77-28.89, crushed dense rocks of fractions 5-10, 10-15 mm 51.49-51.74, nanomodifier powder in form of nanoplates of a mixture of titanium, tungsten, tantalum carbides, obtained by processing carbide waste, 0.12-0.59, water 7.18-7.22.
EFFECT: increase of compressive strength of concrete.
