The corrosion is one of the main deterioration reasons of structural concrete and reinforced concrete. The corrosion is a consequence of unsatisfactory construction maintenances, poor diagnosis of defects' causes and no fracture control of concrete structures and also incorrect repair specifications and incorrect products and techniques selecting for the repair inevitably lead to the concrete structures' deterioration. The most countries are taking care to developing of the national standards for using as manuals for the protection and repair of concrete structures against corrosion to avoid these negative factors. The article authors are offering the comparative analysis of the harmonized Russian state standards and Eurocodes for the protection and repair of concrete structures against corrosion.
