Abstract

Abstract. One of the structural elements of the column of the rectorate building of campus I of UM West Sumatra has experienced cracks in the pedestal area so that the concrete covers are peeled off and the reinforcements are exposed to corrosion. The spread of corrosion is suspected to occur due to exposure to seaside air for a long time. The purpose of this research is to determine the value of half cell potential of 1-st floor column reinforcement in rectorate building and Comparison of the strength value of non-corrosive and corrosive reinforcement bonds. The non-destructive test method was carried out on the corrosion potential test in the area around the exposed column reinforcement using the Half Cell Potential method with Ag/AgCl as the reference electrode. The fc’20.75 concrete sample was printed in the form of a cube measuring 150mm x 150mm x 150mm with ∅19 plain reinforcing steel to simulate the condition of the rebar installed in the field, then tested for binding strength against rebar corrosion that occurred at the age of 28 days in the laboratory. The corrosion potential shows that the reinforcement in the concrete has significant corrosion activity. The strength of the corroded plain rebar bond has a low value of 0.446 and the strength value of the non-corrosive plain rebar bond has a value of 2.421. Keywords: Corrosion Potential, NDT, Bond Test
