Durability is one of the most important requirements for sustainable infrastructure. Federal, state, and local agencies expend significant effort to maintain the quality and condition of aging civil structures, especially those in aggressive service environments. Among many factors, durability influences the service life and integrity of concrete materials and structures. Extensive research has been conducted to understand the deterioration mechanisms of concrete in an effort to extend the longevity of concrete members. In this course, presentations of both experimental and analytical investigations are of interest, which may include the durability of concrete structures reinforced with steel or fiber-reinforced polymer bars, modeling of service life for concrete under aggressive environments, and the structural integrity and resilience of rehabilitated members. The course emphasizes recent research findings and provides an opportunity to discuss present challenges and technical issues. Critical information is given to those who lead tomorrow’s structural design and construction with an emphasis on durability, service life, and integrity, including practicing engineers, government officials, and academics.

The contents of this course include four recorded presentations from the ACI 2021 Fall Virtual Convention.
• Recent Developments and Examples of Concrete Bridges in Florida Using UHPC, FRP Reinforcing, and CFRP or SS Prestressing Strands, Steven Nolan, Florida Department of Transportation
• Modeling the Service Life Performance of Bridge Deck Overlays, by Neal Berke, Tourney Consulting Group, LLC
• Troubleshooting Service Life Predictions: Connecting Construction with Modeling, by Jose Pacheco, CTLGroup
• Remaining Service Life Assessment of Bridge Abutments Using Different Models: Comparative Study, by Abeer Al-Shammari, Advanced Infrastructure Design, Inc.

1. Describe the influence of aggressive environments in the performance of concrete structures.
2. Review the recent advances in research concerning infrastructure durability.
3. Recognize a new direction for the design of concrete structures subjected to environmental loading.
4. Explain how research outcomes are translated into practice.
