FIELD: construction.
SUBSTANCE: invention relates to composition of fibre concrete, used for making precast and monolithic building structures. Concrete mixture, which contains portland cement, microsilica, plasticiser, fibrous filler, sand and water, contains as a plasticiser hyperplasticiser Stachement 2061/151.2, polypropylene fibre as fibrous filler with length of 18 mm and diameter 20 mcm, coarse sand with fineness modulus MK=2.5÷3.0 in non-fraction form with following ratio of components, wt%: portland cement 19.00-22.00, microsilica 1.50-2.50, plasticiser 0.15-0.60, polypropylene fibre 0.02-0.15, sand 65.00-75.00, water - balance.
EFFECT: obtaining fibre concrete with high compression strength, frost resistance and water impermeability at minimal consumption of cement, as well as low cost of composition as a whole.
