Awareness of atypical corrosion mechanisms and potentially corrosive environments can be useful for durable design and developing durability standards. It is known that corrosion of reinforcing steel can occur from excessive chlorides or carbonation. However, corrosion may also occur from less commonly known phenomena or unanticipated exposure (including building interiors). Conversely, some concrete may outlive expected service-life. This course will include presentations of unusual experiences of corrosion activity where it might not have been anticipated or lack of corrosion activity where conditions might lead one to believe it should have been prevalent. Designers, consultants, scientists, and facility managers will benefit.

Table of Contents
1. Identify commonly known mechanisms of reinforcing steel corrosion initiation in concrete.
2. Review current and historical ACI code requirements for corrosion protection as they relate to historical and present expectations of corrosion.
3. Identify atypical forms of corrosion and exposure conditions that may occur in special circumstances, including those where chloride contamination or carbonation levels may not be the primary cause of corrosion.
4. Describe local corrosion on reinforcing steel at concrete cracks and construction joints subject to chloride contaminated moisture leaking through joints and resulting damage on concrete transportation elements.
