| Abstrakt: |
Three concrete blocks instrumented with rebars, anode ladders and other sensors have been produced and exposed to sea water in Fehmarn Belt field exposure site in Roedbyhavn in Denmark. The corrosion activity on the anode ladders is continuously monitored by measurements of half-cell potentials and linear polarisation resistance. The design of the instrumented concrete blocks is presented together with the first results after 2 years marine exposure. Corrosion initiation on anodes with small concrete cover has been identified from the electrochemical measurements and verified by visual inspection. Chloride profiles have been measured for three different binders. |
