HOMER, Ill. (June 24, 2013)--Hundreds of civil engineering students from 23 schools at the annual National Concrete Canoe Competition in Homer, Ill., were challenged to design, build and race canoes made of concrete.
Some of the concrete creations were as long as 22 feet and weighed as much as 180 pounds compared to a wooden canoe of the same size, which weighs about 40 lbs.
Alicia Welling, manager of the California Polytechnic State University team, said the trick to making concrete float is to mix it with glass bubbles and other lightweight objects.
Welling says the three-day American Society of Civil Engineers event last week gave students practical experience in finding creative engineering solutions and working as part of a team.
L'École de Technologie Supérieure, of Montreal, took the title Saturday.
