A concrete canoe is a canoe made of concrete, typically created for an engineering competition.
In spirit, the event is similar to that of a cardboard boat race—make the seemingly unfloatable float. However, since concrete and other poured surfaces are an integral part of a civil engineer's education, concrete canoes typically feature more development than cardboard boats.
Principles Ignoring hydrodynamic effects, all ships or boats float because the weight of the water they displace is equal to the weight of the boat (Archimedes' principle). However, many boats are made of materials that are denser than water, meaning that the boat will sink if filled with water.
Being designed for an engineering competition, concrete canoes often make use of experimental or innovative concrete mix designs or fabrication processes, such as 3D-printed formworks, smart dynamic casting, or 3D-printed concrete.
Most competitive concrete canoes have concrete mix designs that are less dense than water. They must pass a test in which the canoe is filled with water and pushed below the surface; the canoe must then resurface in order to qualify for racing. This is possible because, unlike normal concrete which uses sand and small rocks, concrete canoes are created with porous aggregates such as Macrolite and microspheres. However, because some teams may choose to design their concrete mixes to be denser than water, teams are also allowed to insert concrete-covered, non-structural foam pieces in their canoes to make the canoes float after being submerged.
ASCE National Competition The ASCE (American Society of Civil Engineers) National Concrete Canoe Competition (NCCC) provides students with a practical application of the engineering principles they learn in the classroom, along with important team and project management skills they will need in their careers.
Each year, the NCCC, which is held in mid-June, is hosted by an ASCE Student Organization. Some 200 university teams attempt to qualify for the NCCC by placing first in one of the 18 conference competitions held throughout the United States during the spring. Until 2018, teams placing second in a conference competition behind a university that finished in the top five at the previous year's national competition are also invited. This was replaced by the Wild Card drawing in 2018. If the Concrete Canoe team was part of a student chapter that placed within the top one-third of all annual reports, and the team finished within the top half of all teams in their regional competition, the team was eligible for the Wild Card drawing. Of all qualifying teams, six were randomly drawn to attend the 2018 National Concrete Competition. To be eligible to compete in the Concrete Canoe Competition, the entrant school must be a recognized ASCE Student Chapter or ASCE International Student Group. Typically, frontrunners include University of Alabama in Huntsville, University of Nevada, Reno, University of Florida, California Polytechnic State University San Luis Obispo, the University of California at Berkeley, Clemson University, École de technologie supérieure, Université Laval, and the University of Wisconsin–Madison.
The winners of the ASCE National Concrete Canoe Competition are determined by compiling the team's total number of points from the academic and race portions of the competition. Academic scholarships totaling $9,000 are awarded to the winning teams' undergraduate civil engineering program.
History
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. 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.http://www.concretecanoepictures.com/Concrete_Canoe_Pictures/Correspondence_files/International_Competition.pdf won by the Danish team from Technical University of Denmark. 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.
