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 five recorded presentations from the ACI 2020 Spring Convention:
• Bond Between Steel and Steel Fiber Reinforced Concrete Under Normal and Elevated Temperatures by Amanku Sharma, University of Stuttgart
• Bond Behavior of Carbon Fiber Reinforced Polymers in Ultra High-Performance Concrete by Nariman Khalil, University of Balamand
• Encapsulation Quality of Reinforcement: From Laboratory Tests to Structural Design Guidelines by Pasquale Basso Trujillo, Laval University
• Compressive Bond Behavior of Shape Memory Alloy (SMA) Rebar in Concrete by Muntasir Billah, Lakehead University
• Bond Behavior of Ribbed Iron-Based Shape Memory Alloy Bars Embedded in Concrete, Ghasson Fawaz, University of Texas at Austin 

1. Discuss bond performance of plain and ribbed reinforcing bars embedded in non-conventional concretes, including steel fiber reinforced concrete (SFRC), high strength concrete (HSC), and ultra-high strength concrete (UHPC).
2. Recognize the effect of steel fibers on reinforcement bond strength.
3. Discuss bond performance of concrete test specimens under pullout lab-tests subject to elevated temperatures.
4. Discuss bond performance of shape-memory alloy reinforcement.
