Abstract
The corrosion damage of any reinforced concrete structure is a severe and invisible injury. The corrosion damage can be detected by any electrochemical methods but these methods do not give any perception about the condition of the structure. Therefore in this paper, we had tried to understand the impact echo (IE) responses for noncorroded and corroded rebar (reinforcing steel bar) and established a relationship between impact echo and half cell potential meter. The main objective of this paper is to study the practicability, reliability, and applicability of detecting the rebar corrosion in the concrete block by using the impact-echo method associated with half cell potential meter. For this purpose, we had cast six beams and used an electrolysis process for corrosion of rebar.
