Reinforced concrete is one of the most common materials used by the construction industry worldwide. The raw materials for its construction are widely available and the structures constructed are generally durable. Due to the wide variety of applications, strong concrete structures are vulnerable to a range of threat conditions, including marine, industrial or other critical environments. In fact, the need for high durability is not always achieved in practice due to which the corrosion of reinforcement in concrete occurs which is one of the main causes of deterioration in the RC structure. Corrosion of Reinforcement has been widely reported and is one of the main causes of durability threat in R C structures. In the present study an experimental investigation was carried out on flexural strength of M 20 grade corroded reinforced concrete beams at three different corrosion levels (5 %, 10% and 15%) and results obtained are compared with a non-corroded reinforced beam of similar configuration. It is found that initially (on 5% corrosion) the rate of reduction of ultimate flexural strength is more as compared to more corroded beams (10 % and 15 %).
