FIELD: chemistry.
SUBSTANCE: invention relates to the construction industry and specifically to technologies of preparing a composition of fine-grained concrete mixtures used in making precast and monolithic reinforced concrete articles and structures. The mixture for producing fine-grained steel fibre concrete contains the following in kg/m3: low-water demand binder VNV-70 based on wet magnetic separation wastes -280-290, quartzite sandstone grinding screenings of with particle size not greater than 5 mm 860, Nizhne-Olshansky sand 540, steel fibre 60-65, superplasticiser S-3 1.6-1.7, water - the balance.
EFFECT: high compression and flexural strength, crack resistance and wear resistance.
