Abstract :
Corrosion of steel in concrete is one of the most important factors in the destruction and destruction of concrete structures around the world. Even in advanced countries, this is a year-long issue that will cost a lot of maintenance and maintenance of concrete structures that are sensitive and insensitive to national and national resources. These damage are more severe in the Gulf countries, and many concrete structures have been corroded and damaged. Studies show that the main corrosion agent of reinforced concrete structures is corrosion of steel joints. Therefore, all corners of buildings and structures in corrosive areas should be adequately protected against corrosion. Separating the rebar from the environment and insulating it in terms of contact with corrosive agents is one of the solutions to prevent corrosion and durability of reinforced concrete. Different methods have been proposed for this purpose. In this study, it has been shown that the use of Galvanized reinforcement prevents the corrosion of reinforced concrete meshes effectively and, as a result, reinforced concrete will have a much higher resistance to corrosive environmental factors, such as chloride and sulfate attack. Also, economically, the results show that the cost of using galvanized rebars in sensitive industrial structures, such as oil tanks, is about 6 percent of the total cost, and in conventional buildings, between 1 and 2 percent of the total cost, which is also cost-effective in this regard. Therefore, the use of galvanized bars as a main and effective tool for protecting steel corrosion can be considered by the construction industry.
