|Abstract: ||This study examines the effectiveness of galvanic anodes installed both within the patch
repair and surrounding parent concrete through laboratory testing and on-site monitoring.
Sodium chloride was added during casting of the laboratory concrete specimens to induce
corrosion. The anodes were tested using surface potential mapping at 7 days, 8 months and
also 26 months after repair. Site monitoring of galvanic anodes was performed over a period
of 215 days.
The results showed that galvanic anodes installed in the parent concrete had a greater
polarisation effect on the surrounding steel, which is generally considered to be at highest
risk, as compared to galvanic anodes installed within the patch repair itself. This was in-line
with data obtained from similar installations in full-scale reinforced concrete structures. It
was also noted that, with increasing chloride content, the polarisation extent was reduced.|
