Corrosion condition assessments on historic concrete icons can have challenging parameters set forth prior to establishing testing protocols. Even though concrete is inexpensive and reproducible, the reasons for retaining as much material as possible during the investigation and subsequent repair must be balanced with safety and an understanding of the material conditions. An establishment of corrosion behavior can assist in understanding condition, deterioration, and future degradation. It is imperative to know condition prior to making repair decisions which may have lasting consequences. Three of the four structures discussed in this paper have owners which are cognizant of the historic value of their buildings.
