Ensuring the Efficiency and Durability of Building Structures at Oil Refining Enterprises

When constructing buildings and structures at the oil refining complex under the influence of aggressive environments, the use of high – strength impermeable concretes-high-functional (NSC) and powder-activated (RPC) - becomes particularly relevant as primary protection. At the same time, field tests on the oil fields of Iraq revealed a significant decrease in the strength of structures made of high-functional reinforced concrete by more than 50% at the age of seven years. Dispersed-reinforced powder-activated concretes are characterized by a microporous structure and a minimum number of defects, which makes it possible to open up broad prospects for improving the durability and efficiency of structures. The increased brittleness of RPC is compensated by the introduction of steel fiber into the composition. In this regard, products made of powder-activated steel-fiber concretes are now increasingly in demand. However, its wide application is limited by the lack of a full-fledged regulatory framework and insufficient knowledge of the properties of this material. This paper presents the results of experimental studies of the construction and technical properties of plates made of RPC (Reactive Powder Concrete) and NSC (Normal Solid Concret) under the condition of exposure them to organic aggressive media – kerosene and gas oil. At the same time, the thickness of the plate is a variable criterion that makes it possible to increase the competitiveness of building structures in the oil refining complex.
