Continuous developments in concrete technology and reinforcement materials have been made in recent years to improve the structural performance, durability and sustainability of reinforced concrete. The use of alternative types of concrete and/or reinforcement may affect the bond characteristics of reinforcing bars and, consequently, their development and lap-splice requirements. This session will present recent advances in the characterization of bond and development in new types of concrete and reinforcement, which include ultra-high-performance concrete, fiber-reinforced concrete, shotcrete, high-strength steel, corrosion-resistant reinforcement, and shape-memory alloy bars.

The contents of this course include four recorded presentations from the ACI 2020 Spring Convention:
• Bond Slip Behavior Between Geopolymer Concrete and Deformed Steel Bar, by Maria Aiello, Universita del Salento
• Advances on Bond of Embedded Steel Reinforcement in the New Model Code (fib) 2020, by Givanni Metelli, University of Brescia
• Bond of High-Strength Reinforcement in Joints of Earthquake-Resistant Concrete Moment Frames by Rémy Lequesne, University of Kansas
• Bond Performance of Alternative Reinforcement in Concrete by Sachin Sreedhara, Clemson University

1. Recognize bond performance of alternative types of concrete and reinforcement.
2. Identify open issues on bond of reinforcement in new and existing structures.
3. Explain the relevance of bond of reinforcement in structural performance and design.
4. Learn about the relation between crack control and reinforcement bond.
