mechanical and corrosion behavior of reinforced concrete structures . The protection of steel rebar prior to its installation into the concrete is of great importance for the durability of concrete structures and prevents great economic loss. Among the available protection systems for steel, the use of coatings is the most popular and
Single-story, multi-story, skyscrapers, factory buildings, warehouses, waiting rooms, all made of the steel structure. However, steel as a building material has some unavoidable defects in fire prevention. Its mechanical properties, such as yield point, tensile strength, and elastic modulus, will decrease sharply due to temperature rise.
Steel bars embedded in reinforced concrete are vulnerable to corrosion in high chloride environments. Bidirectional electromigration rehabilitation (BIEM) is a novel method to enhance the durability of reinforced concrete by extracting chloride out of concrete and introducing an inhibitor to the surface of the steel bar under the action of an electric field.

material used and the environment to which the structure is exposed, durability may also be significantly longer. For example, when metalizing a steel structure in a splash zone, zinc consumption is 2-3 µm per year. If the thickness of the metalizing zinc coating is 250 µm the protection provides an expected lifespan of between 85 and 125 years.
