What’s Concrete But Floats Like a Boat?
The Mizzou Concrete Canoe Team builds a 215‐pound canoe. It floats — barely.
Leave it to engineering students to push common materials into uncommon forms. About 15 members of Mizzou’s Concrete Canoe Team row, row, rowed their boat to third place at a regional American Society of Civil Engineers contest April 21 in Lincoln, Neb. The lightweight concrete craft weighs in at 215 pounds with a density of 61 pounds per cubic foot, which is slightly less than that of water. It floats, but just barely. And how does a concrete canoe handle? Says team co‐captain Zach Treece: “Like a plow in the water.”
