Corrosion of reinforcement is a relatively common and serious threat to the safety of the structure durability, the durability of the reinforced concrete is caused by the damage of the most important and direct factor, is also one of the main forms of durability of concrete structure damage. This paper introduces the function of reinforced concrete, steel corrosion reasons, steel corrosion on the durability of structures， and reasons for the corrosion of reinforcement is proposed to improve the structure durability and corrosion prevention measures, and finally wrote to the development prospect of reinforced concrete durability. Keywords:Steel corrosion; The durability
