Abstract:

To facilitate the shotcreter’s task, partial or full automation of the placement process is of interest, which is why the Shotcrete Laboratory at the Université Laval, Québec, QC, Canada, acquired a six-axis robotic arm in 2019. The arm can repeat predefined spraying patterns with practically flawless accuracy. This robot, combined with a data acquisition system that measures rebound during a standardized spraying session, is the starting point of a large research project, “SPARO – Shotcrete Placement Automated by Robot."

Abstract:

In July 2024, GeoStabilization International used shotcrete for the construction of a soil nail wall for a large data center in Atlanta, GA, USA. To enhance efficiency, GeoStabilization implemented innovative techniques, including the use of a shotcrete robot. This proved especially effective during the installation of the initial structural layer of the wall.

Abstract:

Tunnel linings are typically curved structures placed in direct contact with and restrained by the surrounding ground. The main objective of this two-part article is to explain how tunnel linings can be designed and analyzed in a reasonable and rational manner that is consistent with tunnel lining behavior. Part 1 focuses on design considerations and a brief history of tunnel linings.

Abstract:

Over the last four decades, fibers have been used as a full or partial replacement for conventional reinforcement in slabs-on-ground, pavements, overlays and topping courses, shotcrete, precast concrete, and structural elements. The article summarizes documents related to fiber reinforcement, benefits of using fibers during construction and service, and design with fiber reinforcement.
