Durability Characteristics of Reinforced Concrete Column

Abstract: The corrosion of steel reinforcement in concrete is the most significant durability problem encountered in reinforced concrete structures. In moist air reinforcement corrosion is an obvious cause of deterioration of concrete structure, which affects the durability and service of reinforced concrete structure. The deterioration of concrete structures caused by corrosion of reinforcing steel bars is not always directly related to strength reduction of reinforcing bars. When corrosion of reinforcing bars takes place crack formation in concrete could lead to greater reduction in strength and durability.
