Presentation Title

Historical Advancements in Corrosion Control of Existing Conventionally Reinforced Concrete Structures in the United States Towards a Sustainable and Viable Future

Presentation Synopsis

After a brief and self-indulgent trip back to the time of Sextus Julius Frontinus (circa 40-103 AD) to hear in his words some of the challenges with maintaining and repairing Roman aqueducts, this presentation explores the historical development of corrosion control methods for existing concrete structures in the United States (and some other places) during the 20^th century, and then touches on related topics that will likely be important in the future.  Historical aspects of corrosion science, service-life models, coatings, cathodic protection and corrosion inhibitors are discussed, as well as the introduction of some of the more relevant associated industry standard guides.  Likely future considerations, importance and key questions associated with safety, sustainability and technology are also discussed.  For some, this presentation may serve as a trip down memory lane, and for others a glimpse of how we got where we are, what we might see in existing structures we assess and repair, and where we are going as an industry.
