As we are getting geared for nationals, our team decided that it would be good to get some more canoeing practice in before everyone went their separate ways for the summer. Here are some pictures from "Canoe Camp 2012".

We drove up to Bear Lake on Friday night and played volleyball, frisbee, and had a campfire when it got dark. Getting the fire started was an adventure, but we all survived and had a great time. 

We got up bright and early Saturday morning and started our day with a wonderful breakfast.

Our team had the opportunity to do some service as well.  While the racing teams got ready to practice, some of the other team members helped one of our own with her wedding announcements. 

We began practicing,

 were cheered on,

 and shown the new endurance race.

A couple of our team members were cold a tired, so they decided to take a nap in the canoe box.

We finished the day strong with the coed team and we are so excited to participate at nationals. 

ASCE Rocky Mountain Region Conference 2012

Well, we made it to regionals and were very excited to compete against the other teams. Following are pictures of events that the canoe team participated in, in chronological order.

First was "Canstruction", which we did not do very well in (as you can probably see).  Points in this category are just for participation. All cans were donated to a local food bank following the event.

Swamping the canoe.  We had to completely submerge the canoe to make sure that our concrete design would float and assure that there were no holes in the canoe.

 Racing. We took first in the Women's Sprint, Men's Sprint, and Men's Endurance and third in the Coed and the Women's Endurance.

Don't worry, we are still #1.  

 Finally, our reclaimed trophy. Great job to everyone who participated! The canoe team is now headed to the National Concrete Canoe Competition in Reno, NV from June 13 to the 16. We would also like to say good luck to the Steel Bridge Team at their national competition later this month! 

After all our sanding was done, we were lucky enough to get a wonderful artist to "paint" our canoe with concrete stain. He did a wonderful job, and with the final coats of sealer that were polished, our canoe is looking ready to win some competitions.

In keeping with the theme of our canoe this year, there is a rendition of "Old Ephraim" inside the canoe. There are also scenes from Cache Valley on the outside and the name, Old Ephraim, in block letters along the bottom of the canoe.

With the hours of paddling practice we have put in, we feel confident about competing this weekend and the ASCE Conference for the Rocky Mountain Region. We will do our best both in the competition and in representing our school as best we can. Go Aggies!!

After the canoe was done curing, we had to remove the foam mold from the canoe.

So we dug,

and dug, until all the foam was removed.

Then we gathered the foam into large garbage bags for recycling.

After the mold was removed, we sanded, and sanded, and sanded. We gradually worked our way to using finer sandpaper until the canoe was so smooth it glistened.

After the mold was constructed, we could then cast our canoe onto the form. This was a big project that took us about 4 hours to complete.

We measured, and mixed concrete.

Then, we put a layer on our mold.

A layer of mesh over the first layer,

another layer of concrete,

checking our dimensions,

and finishing.

Once this was all completed, we placed sheets on top to distribute the water from a sprinkling system overhead. The water from this helps create a stronger concrete. The canoe then cured for 28 days.

Next phase: Mold construction. The rules this year just require maximum dimensions for the canoe, so we tried a more streamlined shape than we had last year. This is how we constructed our mold:

We cut tin cross-sections.

We used the tin as a template for cutting foam sections.

We arranged our foam sections on a table.

We sanded the foam, and put putty on it and sanded some more.

We put a Styropoxy coating to keep the concrete from bonding with the foam.

After all of this, our mold was finally ready for concrete.

Do we look like scientists?

Tensile Test

Compression Test

Crushed Cylinder after compression

Float Test

Cylinder Molds

First step to building the canoe: Create a mix design. So we created some, made cylinders, tested the cylinders, and then created new mix designs. This process finally came to an end when we found a design that was light enough, but strong enough for our requirements.
