• Abstract:
  Four bridge decks were overlayed and patched and one bridge pier was patched using concrete with and without corrosion inhibiting admixtures. Some concrete surfaces received topically applied corrosion-inhibiting treatments prior to placement of the concrete. The repairs were successfully completed, and the initial condition of the repairs is good. Corrosion probes were installed in many of the repairs, and measurements are being made each quarter to determine macrocell current, macrocell potential, and resistance. The probe indicates that corrosion is occurring in repairs done with and without corrosion-inhibiting treatments. No conclusions can be drawn at this time, and the study will continue for a total of 5 years.
