Paper Title:

Experimental Studies on the Prediction of Corrosion Levels in Reinforced TMT bars in SCC Exposed to Marine Environment

Abstract: Reinforced concrete structures have good potential to be durable and capable of withstanding adverse environmental conditions. Failures in R.C.C structures do still occur as a result of premature reinforcement corrosion. Corrosion of steel has been recognized as one of the major durability problems in R.C.C structures. Damage due to corrosion of steel bars considerably reduces the strength, serviceability and life of structural components. Inspection and continuous monitoring techniques are necessarily to be carried out to assess the steel corrosion in buildings and bridge components in order to ensure their safety, durability for longer time. These techniques are essentially required for easy maintenance and repairs of the structural components also. Few investigations were carried out to study the corrosion levels in reinforced steel bars exposed to marine environment. Very few investigations were carried out so far to predict the corrosion levels in SCC exposed to salts and chemical environments. The present paper outlines the investigations carried out to predict the corrosion levels in TMT bars in Normal Conventional Concrete (NVC) and Self compacting concrete (SCC) exposed to marine environment . It also shows the severity of concrete exposure condition on the progressive corrosion in TMT bars when immersed in salt solution.
