Shotcrete Today — State-of-the-Art

Abstract: A brief introduction to shotcrete history, processes, materials, equipment, placement, and testing. We will cover current shotcrete placement technology and advances we may see in the future. We will describe the ICRI, ASTM, and ACI codes and standards that address shotcrete placement for structural concrete and repair. Finally, we’ll address the benefits of certification of shotcreters (formerly nozzlemen) and shotcrete inspectors, and the need for qualified shotcrete contractors.

Learning Objectives:

1. Learn the aspects of both wet and dry-mix shotcrete processes.
2. Recognize ACI shotcrete reference materials and other Industry standards pertaining to acceptable shotcrete placement.
3. Understand the standards provisions for shotcrete placement in structural concrete
4. Appreciate the need for certified shotcreters and inspectors, as well as qualified shotcrete contractors.
