Modern infrastructure activities are not possible without the use of reinforced concrete and thus the strength anddurability of these structures is important. Corrosion of reinforcing steel is been cited as the most detrimental effect and is thusendangering the structural performance in terms of load bearing capacity and durability. The corrosion affects the service life ofstructure. The bond between reinforcement and concrete is affected due to corrosion and thus the strength of RCC alsodeteriorates. Corrosion of reinforced concrete is a slow process. The concrete acts as a protective shield thus, it takes reasonablylong time for corrosion initiation and progress. The accelerated corrosion technique is a method to assess causes and extent ofcorrosion. The diffusion of chlorides in concrete is recognized as one of the major cause for initiation of corrosion phenomenon.This report presents study on effect of corrosion on compressive strength, flexural strength and torsional strength of reinforcedconcrete beams. In this experiment M25 grade of concrete is used for casting of RC beams. Universal testing machine (UTM) is usedfor compressive strength test and flexural strength test and specially prepared setup is used for torsional strength.
