University of Washington Concrete Canoe Team

Regionals, 2014

Welcome

Welcome to the University of Washington Concrete Canoe Website! We are a student run group associated with the University of Washington Civil and Environmental Engineering Department and the American Society of Civil Engineers. Each year, we design, construct and race a concrete canoe, competing against other colleges in a variety of categories. If you're a student looking to join us, send us an email at uwconcretecanoe(at)gmail(dot)com or stop by one of our meetings listed on our events page. If you are an individual or part of a company looking to support us, visit our "Donations" page to help!

What is a Concrete Canoe?

A concrete canoe is exactly what it sounds like - a canoe made out of concrete! The catch is that the canoe doesn't just float due to displacement of water because our concrete is actually lighter than water! When the canoe is completely swamped with water, it still floats. This is the result of a combination of factors: The concrete used is entrained with air pockets and uses aggregates that are also lighter than water to decrease the density. Instead of the gravel used in typical concrete, different types of glass, plastic, and styrofoam are used as aggregate. We also use environmentally friendly replacements for cements and aggregates including slag and recycled glass beads.

Why Build a Canoe out of Concrete?

Building a concrete canoe is fun, challenging, and extremely rewarding. It's an opportunity to get hands-on with a material that is commonly used in civil engineering applications. No other engineering majors work with concrete to the extent that we do, making the exploration of the extents of concrete’s abilities a uniquely civil engineering challenge. By getting this hands-on opportunity, we learn more about the material, which will allow us to be better prepared to design and work with concrete in our future careers.

Although concrete canoe is a learning experience, fun also comes in many forms on the team - Some people enjoy simply getting their hands dirty and working with the concrete mixes. Others appreciate the camaraderie of working towards a common goal and social aspect of the club. Finally, others enjoy the opportunity to train in Lake Washington for the competitive races. These people are the lucky paddlers that get the chance to race in our finished product.

There are many challenges that are associated with the concrete canoe team. The biggest challenge comes from the material itself - Concrete can be a fickle material to work with since changing any one characteristic can have a cascading effect on the rest of the material's characteristics. It can also be difficult to place the concrete on vertical slopes for the edge of the canoe when it's too wet. However, if the concrete gets too dry, it's impossible to place. There's always a balance that has to be found.

Finally, the team comes together through all of the hard work, sweat, and tears to produce the final product. Seeing the completed canoe on display at Regionals and Nationals can be one of the most rewarding sights of the entire year. Still, it's not all about the competition. This team is also about learning and having a good time. In the end, it's all about the knowledge gained and the memories created over the entire process.
