During the construction and operation of oil and gas industry facilities, there are increased requirements for the quality of concrete. To this end, it is necessary to use new formulations and their preparation technology to obtain concretes of the required density with high strength, frost resistance, water resistance, crack resistance and, ultimately, increased durability. The use of a superplasticizing additive, basalt or polymer fiber and a nanocarbon additive in the specified amounts in the composition of fine-grained concrete contributed to an increase in the uniformity and density of the mixture and, accordingly, an increase in the strength characteristics of concrete at various hardening times. As a result of testing concrete samples for frost resistance, a mark of 400-500 cycles of freezing and thawing was obtained. This makes it possible to use these compositions of fine-grained concrete in harsh climatic and difficult engineering and geological conditions of construction and operation of oil and gas industry facilities.
