A Decade of Shotcrete Research at Laval University
This paper presents some of the most interesting outcomes of over a decade of shotcrete research at the Department of Civil Engineering, Laval University (Quebec City, Canada). While focusing mainly on dry-mix shotcrete, the paper also covers experimental work done on fresh and hardened properties of wet-mix shotcrete. Topics presented include rheological interpretation of the influence of fresh properties of shotcrete on placement and performance, effects of certain mixture design parameters (presence of accelerator, use of air-entraining admixture, etc.) on strength and durability, and effect of reinforcement encapsulation on performance. Key experimental observations, typical results, and recommendations are presented. Illustrations from actual field practices as well as ongoing research are provided.
