MINI SESSION: Shotcrete: A Very Challenging High-Strength Concrete
Sunday, October 17, 2021 2:00 PM - 3:00 PM
When shotcrete is chosen for a project, it usually means very challenging performance requirements in workability, durability and especially a very high early strength. This high strength concrete requires singular care to assure a successful project.
This session will present the experience of designers, producers and quality control experts sharing their perspective on the challenges and current solutions in specifying, obtaining and assessing properties in high strength shotcrete.
(1) Recognize the challenges faced in specifying high strength shotcrete;
(2) Recognize the influence of the constituents and mixture design in obtaining a successful high strength shotcrete;
(3) Identify the challenges in quality control;
(4) Review and learn from the experience of actual projects developed using high strength shotcrete.
This session has been approved by AIA and ICC for 1 PDH (0.1 CEU). Please note: You must attend the live session for the entire duration to receive credit. Mini Sessions will not be available on-demand.
