ACI 222R, the Guide to Protection of Reinforcing Steel in Concrete against Corrosion, is the flagship document of the ACI 222 Committee. The new version of the document is the first major revision since 2001 and comprises the latest state-of-the-art. It presents with a practical emphasis the mechanism of steel corrosion in concrete, corrosion protection in new construction, condition evaluation, and remedial measures to mitigate corrosion in existing structures. The course contains presentations from subject experts on critical topics from the ACI 222R document, such as anode and cathode reaction, chloride threshold research, epoxy coating reinforcement, galvanizing reinforcement, stainless steel reinforcement, waterproofing surface membranes, polymer concrete overlays, portland cement concrete overlays, and latex-modified concrete overlays, allowable chloride limits.

The contents of this course include five recorded presentations from the ACI 2019 Fall Convention:
• Overview of the 222R Guide to Protection of Reinforcing Steel in Concrete against Corrosion, by O. Burkan Isgor, Oregon State University
• Mechanisms of Corrosion of Steel in Concrete - Principles of Corrosion, by Carolyn Hansson, University of Waterloo
• Mechanisms of Corrosion of Steel in Concrete - Reinforcing Bar and the Concrete Environment, by Michael Brown, WSP USA
• Protection Against Corrosion in New Construction - Design Approaches and Choices, by David Trejo, Oregon State University
• Protection Against Corrosion in New Construction – Methods for Excluding External Sources of Chloride form Concrete, by Neal S. Berke, Tourney Consulting Group, LLC

1. State the fundamental principles of the corrosion mechanism of reinforcing steel in concrete.
2. Identify the methods of corrosion protection in new construction with special emphasis to design approaches, choices, and corrosion control techniques.
3. Recognize corrosive environments and active corrosion in reinforced concrete structures and select condition evaluation strategies.
4. Explain remedial measures to mitigate reinforcement corrosion in concrete structures.
