Abstract

Over head water tanks, made up of reinforced concrete are more common due to the fact that it can be easily cast in any desired shape and size. The durability of such tanks may get affected due to external agents like wind, air etc. and needs maintenance periodically. The corrosion of reinforcement is the major distress of any reinforced concrete structure, and these tanks also face the same problem. Once the corrosion of steel happens, the satisfactory performance of the reinforced concrete tanks gets affected and distress starts in the form of minor cracks. If left unchecked, the effects of corrosion may propagate further and may lead to structural failure in due course. In this case study, many overhead tanks made up of reinforced concrete were studied, and their types of distress along with remedial measures are suggested.
