Corrosion Resistance in Reinforcement
Why Corrosion Control of Reinforcement bars (Rebars) is necessary? Corrosion control of steel reinforcement is necessary to prevent damage and failure of concrete structures. Nearly 40% of failure of concrete structures is due to corrosion of embedded steel reinforcement There can be many causes for corrosion of reinforcement, but mostly it is related to the quality of concrete, environment, and quality of construction practices. So, the first step in corrosion control of rebar is to provide good quality of concrete through good construction practices. The quality of concrete materials, mixing, placing and compaction techniques and good workmanship can help control the rebar corrosion.
