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 five recorded presentations from the ACI 2021 Fall Virtual Convention.
• Durability of Internally Cured Concrete with Supplementary Cementitious Materials, James Lafikes, Genesis Structures
• Corrosion Related Durability of Steel Reinforcement in a Novel Concrete Material, by University of South Florida
• Influence of Nonionic Surfactants on Structure, Reactivity and Efficiency of Montmorillonite in Mitigating Alkali Silica Reaction, by Jianqiang Wei, University of Massachusetts Lowell
• pH-Dependent Chloride Desorption Isotherms of Portland Cement Paste, by Mahmoud Shakouri, Colorado State University
• Development of a Standard Practice for Service Life Prediction, by Kyle Stanish, Tourney Consulting Group, LLC

1. Define the state of the art of structural performance subjected to environmental and mechanical distress.
