Over winter break, we finalized our concrete mixture. We first narrowed our mix design down to five different mixes. The compressive strength of each mix was tested. We then choose our final design based on the workability and compressive strength of each mix. Our canoe dimensions were uploaded from MaxSurf to AutoCad. From AutoCad we were able to take section cuts along the length of the boat in order to create a mold for the canoe. Once we got back from break, we were ready to start making the mold.
