Concrete canoe

Concrete Canoe competition in the United States began in the 1960s, when a small number of ASCE student chapters began holding intramural Concrete Canoe races. Then, in the 1971, the University of Illinois at Urbana-Champaign held the first intercollegiate race against Purdue.[5] In the more than 45 years since, the students’ efforts to combine engineering excellence and hydrodynamic design to construct water-worthy canoes have culminated in an advanced form of concrete construction and racing technique known as the “America’s Cup of Civil Engineering.”

In 1981 as part of the FIP congress in Stockholm, Sweden there was the 1st FIP international concrete canoe race.[6] won by the Danish team from Technical University of Denmark.[7] inspired by Herbert Krenchel

In 1988, ASCE expanded the competition to the national level, when Master Builders, Inc. (now known as BASF) signed-on to become the sole corporate sponsor for the event. In its first year, 18 teams of enthusiastic civil engineering students from the nation's premier academic programs gathered in East Lansing, Mich., to test the waters of this innovative and educational event. Over the next two decades, the competition became a great success, with regional winners traveling across the country by plane, train and Ryder truck, canoes in tow, in their quest to become National Concrete Canoe Competition champions.

As competition was developing in the United States, the idea had also taken hold in other countries. Today, concrete canoe racing happens around the world in places like Germany, South Africa, Canada, Japan and the United Arab Emirates; and with sponsorship from ASCE and the American Concrete Institute (ACI), the 2007 National Concrete Canoe Competition winning team, University of Wisconsin - Madison, travelled to the Netherlands to represent the United States in the 30th Annual Dutch Concrete Canoe Challenge.

The Concrete Canoe Competition is designed to provide civil engineering students with an opportunity to gain hands-on, practical experience and leadership skills by working with concrete mix designs and project management. Organizers, sponsors and participants are dedicated to building awareness of concrete technology and application, as well as the versatility and durability of concrete as a construction material, among civil engineering students, educators, practitioners, the concrete industry and the general public. They also strive to increase awareness among industry leaders, opinion makers and the general public of civil engineering as a dynamic and innovative profession essential to society. In its history, the National Concrete Canoe Competition has challenged the knowledge, creativity and stamina of more than 400 teams and 5000 students. In 2008, more than 200 teams competed in 18 conference competitions to qualify for participation at the national level.

Sponsors include BASF, Kiewit Corporation, American Concrete Institute, Holcim, Bentley Systems, Cemex, and Propex.

Teams of engineering students will gather for a weekend designed to be both challenging and fun. Twenty-five percent of each team's total team score will be based on the engineering design and construction principles used in the creation of their concrete canoe; 25 percent will be based on a technical design report detailing the planning, development, testing and construction of their canoe; and 25 percent will be based on a formal business presentation highlighting the canoe's design, construction, racing ability and other innovative features. The remaining 25 percent of each team's score is based on the performance of the canoe and the paddlers in five different race events: men's and women's slalom/endurance races, and men's, women's and co-ed sprint races.

For the purpose of the competition, concrete is defined as a mixture of cement, of which at least 30% (by mass) must be Portland cement, and aggregate, which must constitute at least 25% (by volume) of the mix. The aggregate need not be conventional construction aggregate (sand, etc.), but may include materials such as hollow glass beads and fibers. Epoxy is not permitted. Up to 50% of the thickness of the canoe may be a reinforcement mesh.

Concrete canoe teams must design their canoes from scratch. Typically they create the shape of the hull with a computer design program specifically made for yachts, canoes, and other watercraft. The shape is optimized for racing. This hull shape is then given to a construction team, responsible for making a mold for the canoe to be formed on. A special concrete mix is designed over several months, emphasizing among other qualities, an optimal balance between strength and low density. The finalized mix design is placed on the form; the hull thickness usually ranges from about 3/8" to 3/4". Teams later spend hundreds of hours sanding and applying exterior graphics to their canoes for a nice finish. Scoring in the competition is based on the quality of construction, race performance, a design paper, and a business presentation.
