Abstract

An experimental work was carried out to study the influence of impressed current on residual bond strength of corroded specimens. In accelerated corrosion process, two different current densities 0.08 mA/cm2 and 0.4 mA/cm2 were used which identified as 18slow 19 and 18fast 19 current. Beam end type bond specimens reinforced with 10 mm and 16 mm bar diameter were prepared for the bond test. Stirrups were provided along the main bar. Corrosion level of the main reinforcement was limited to 8% theoretical section loss. Other parameter such as the location of the test bar (corner and centre location) was also considered. The results indicate a significant influence of impressed current on the crack width with the 18fast 19 current tended to have wider crack than the 18slow 19 current. The influence on bond strength and other related parameters are being discussed
