THE IMPACT OF MINERAL OILS ON THE LOAD-BEARING CAPACITY OF COMPRESSED REINFORCED CONCRETE ELEMENTS

Statement of problem. Reinforced concrete elements are widely used in modern construction due to their exceptional mechanical characteristics, such as strength and long-term operational stability. However, under the influence of aggressive environments, including industrial lubricants and mineral oils, their load-bearing capacity can significantly deteriorate. Oils penetrate the porous structure of concrete, altering its physical and chemical properties, which negatively affects the material's strength and its ability to withstand mechanical loads. Since reinforced concrete in many industrial facilities is in permanent contact with mineral oils, there is an urgent need for a comprehensive study of their impact on concrete and reinforced concrete elements. Purpose. The aim is to review current scientific research and theoretical approaches to assess the impact of mineral oils on the load-bearing capacity of compressed reinforced concrete elements. The article reviews research findings that confirm the impact of oils on corrosion processes and crack formation in reinforced concrete, as well as recommendations for protective measures to improve the durability of structures. Conclusion. A review of scientific sources indicates that oils play a significant role in industrial processes, but prolonged contact with reinforced concrete structures can lead to a considerable reduction in load-bearing capacity. The results of scientific research confirm the need for further study of this phenomenon and the development of protective measures aimed at minimizing the negative effects of mineral oils.
