With the increase in demand for construction materials, man has improved a lot in the construction techniques of structures. Reinforced concrete beams are normally designed as under reinforced to provide ductile behavior such as the tensile moment of resistance. In coastal environment reinforcement corrosion is an obvious cause of deterioration of concrete structure, which affects the durability and service of reinforced concrete structure. Structural stability is majorly influenced by strength of concrete. Torsional strength is a measure of the shear strength of concrete, in other words it is a measure of a resistance against failure in twisting. The main aim of this study is to analyze the flexural, shear & torsional strength, experimentally; of corroded beams using Ordinary Portland cement. Accelerated corrosion technique was adopted to corrode the beam experimentally. We have used varying percentage of corrosion as 0%, 2.5%, 5% and 7.5%. Change in strength of RC beams is studied for varying percentage of corrosion. Beam specimens are prepared using M20 grade concrete for OPC. Beam specimens casted are tested in UTM for flexure and shear. Specially prepared loading setup is used for torsional strength test.
