FIELD: construction.
SUBSTANCE: invention can be used in the manufacture of monolithic and precast concrete products and structures. Fiber-reinforced concrete mixture comprises wt.%: portland 26.85-27.8, quartz sand 53.7-55.6, high modulus fibers - steel fiber wave profile of wire and amorphous metallic fiber in the ratio 1 : 0.4 - 2.4 respectively, with a total percentage by volume of reinforcement of 1.5 - 2.5%, 5,4-8,7, water - the rest.
EFFECT: increasing tensile strength in bending and crack resistance of concrete fiber obtained from fiber-reinforced concrete mixture.
