The results of the development of compositions and technologies for their preparation for use in the structures of marine gravity oil and gas production platforms and underwater oil and gas pipelines are presented. The efficiency of using basalt fiber fibers, plasticizing additive "Sika ViscoCrete 5-800" and soot waste from thermal power plants in the manufacture of fine-grained concrete is proved. As a result of the experiments, the strength characteristics of fiber concrete were determined depending on the amount of superplasticizer and soot waste introduced when using equal-moving mixtures. An increase in the compressive and Flexural strength of samples modified with basalt fiber, superplasticizer and industrial waste is shown, which contributes to an increase in the operational characteristics of oil and gas offshore structures by increasing the parameters of frost resistance and water resistance of structural materials.

Keywords: oil and gas facilities, fiber-reinforced concrete mixture, the superplasticizer basalt fibre, particulate waste strength
