CHARACTERISTICS OF THE REINFORCED CONCRETE CONSTRUCTIONS AND STRUCTURES OPERATED IN THE COASTAL ZONE OF THE BLACK SEA COAST
Journal Title: International Journal of Civil Engineering and Technology - Year 2019, Vol 10, Issue 3
Abstract
Concrete and reinforced concrete are used for the construction of buildings and structures with long-term operation. The use of structures made of these building materials is massive, and more than 4.5 billion m3 per year of concrete and reinforced concrete are produced in the world to meet the requirements in the building industry. During operation, structures are often exposed to adverse environmental effects (aggressive chemicals in the form of gases, salt solutions and aerosols, microorganisms) and turn out to be in difficult working conditions. These effects contribute to the destruction of materials and reduce the durability of structures, which in some cases may fail within a year or even months after the start of operation. When building objects are located near industrial enterprises and on the coast, the impact of adverse factors may increase. The article presents the results of a study of the content of inorganic salts and the species composition of microorganisms in the surface layer of concrete in reinforced concrete structures operated on the Black Sea coast. The authors presented the results of the study of samples of concrete taken from the structures of the pier, which was in direct contact with sea water, depending on elevations relative to sea level and orientation to the cardinal points. The results of the study of samples taken from the structures of the fence, located at a distance of about 50 m from the coastal edge, depending on the orientation of the fence on the cardinal points and its parallel or perpendicular position relative to the coastline were also obtained. A correlation was found between the levels of salt content and the types of microorganisms inhabiting the surface layer of concrete in coastal structures. It has been established that under the influence of the sea climate, a simultaneous impact on building structures of high air temperature, solar radiation, wind, biological environment, moisture and impurities of hygroscopic sea salts in the air occurs.The intensity of the impact of negative factors depends on the elevations of the location of the structures relative to the surface of the water and their orientation relative to the coast and to the cardinal points.
