Review study towards corrosion mechanism and its impact on the durability of concrete structures

This paper imparts a review study on the causes and factors responsible for corrosion, its initiation and propagation mechanism inside the structures, leading to a better discernment of the problem associated with the durability of the existing structures. This study employs all necessary informatio...
