Lightweight Shotcrete Canoe: Use of Viscosity Modifying Admixture and Acetone as Artificial Paste
Publication: Journal of Materials in Civil Engineering
Volume 18, Issue 3
Abstract
This paper presents some of the most interesting steps followed by the Canadian team from Laval University in developing a high tensile strength, lightweight concrete for the construction of their canoe. This mixture was used in 2004 by the Laval University Concrete Canoe Team, which, year after year, participates in an engineering challenge. The objective is to develop a concrete mixture that can be pumped and shot on a male mold using a custom shotcrete technique. The 2004 mix contains acetone to enhance its fluidity and Welan gum to increase its viscosity, thus preventing segregation.

Acknowledgments
The authors would like first to thank the ASCE and Master Builders, who sponsor the competition organization. The authors also want to thank all the Laval University Concrete Canoe Team members ⟨http://canoe.gci.ulaval.ca⟩, who have worked hard on the canoe development, with a special thanks to Vincent Lapointe, Alexandre Godin, Vanessa Durand, and Dennis Burns, who have worked very hard on the concrete mix development. A special thanks also goes to the concrete canoe sponsors, who made this project possible.
