Abstract

Reinforced concrete structures expo-sed to marine environment are subjected to a series of electro chemical deterioration processes. In view of the immense cost involved in initial construction, repair and rehabilitation, it’s quite important that these structures have a long service life and be able to resist the effects of the harsh environmental conditions with minimum maint-enance cost. In order to improve the service life of these structures it is necessary to study the effects of bond strength and corrosion of rebars in concrete which is focused in this study. Both pot- able water and saline water were used in the study. Pull out tests were conducted as per IS2770:1967(Part-I) on specimen subjected to accelerated corrosion. Specimens were of concrete grade M20, M25, M30 and steel grade Fe500D with 16mm diameter. Two different types of corrosion inhibitors were also used to study the change in corrosion resistance in the specimen.The Bond stress variation with the change in grade of concrete, type of corrosion inhibitor and pH of water used in concrete are also studied.
