Abstract

This paper studied the effects of reinforcement corrosion on bond performance between G-35 concrete and 16mm reinforcing steel for different corrosion levels. The steel rebar embedded in concrete specimens were corroded using an electrochemical accelerated corrosion technique by impressing current to the specimens to develop the different mass losses of reinforcement bars after corrosion. Then, monolithic pull-out loading tests were carried out on the specimens to develop the bond strength which is an important property in concrete construction as it determines the amount of tensile stress a concrete member is able to withstand safely. Bond-slip relationships for the different corrosion levels were compared. The achieved mass losses of rebar were compared with theoretical mass losses obtained by Faraday's law.
