FIELD: chemistry.
SUBSTANCE: invention relates to industry of building materials, in particular, to production of fine-grained concretes, which can be applied in low-rise building. Raw material mixture for concrete production, contains, wt %: Portland cement 27-30, fly ash 27-30, wastes of diamond dressing, which are characterised by mineral composition, wt %: serpentine 70.0, calcite 2.0, dolomite 28 38.5 - 44.9, super-plasticiser C-3 1.1 - 1.5, with water-cement ratio 0.4 - 0.45.
EFFECT: reduction of Portland cement consumption in composition of raw material mixture for production of concrete with preservation of its strength.
