| Summary: | Modification of concrete composites includes the manufacture of a concrete product, followed by its impregnation with monomers such as styrene and methyl methacrylate, capable of curing in concrete pores. However, despite the high efficiency of concrete modification with polymers, their production is hampered by the complexity of the technology associated with the toxicity and explosiveness of these impregnating materials. The article proposes to use technical vegetable oil as an impregnating material. The study showed that the treatment of concretes with technical vegetable oil (TVO) reduces their water absorption to less than 1%, strength by 40%, and frost resistance by an order of magnitude.
