Abstract
Corrosion is the degradation of a metal by an electrochemical reaction with its surrounding environment. The corrosion of embedded steel reinforcement in concrete causes durability issue in reinforced concrete structures and cement concrete pavements. The impact of corrosion of embedded steel rebars on the performance of reinforced concrete structures and pavements is a subject of concern for the engineers and scientists working in the construction industry. One of the effective ways of studying such influence is to understand the effect of corrosion on the mechanical and durability properties of concrete. The bond strength between steel rebar and concrete is also an important parameter of study. This study focuses on probing the effect of corrosion on bond strength and other mechanical properties of reinforced concrete. A pull-out test was conducted on 18 concrete cube specimens having steel bars of 12 and 16 mm diameter Fe500 grade. These bars were corroded with the help of commercial grade hydrochloric acid solution 10% v/v. Each group of bar specimens included three levels of corrosion: 0, 3 and 5%. Tension test on steel bars and compression test for concrete cubes were conducted.
