Today is the busiest day of the Concrete Canoe Team! It is the day when the club actually casts the actual canoe for the competition. This process usually takes up an entire day and will require as much help as possible.
The Concrete Leads and the mixing team will ensure that the rest of the team has a continuous supply of concrete to cast. Pre-bagged concrete mixes make the mixing process easier on casting day.
The rest of the team focuses on casting the concrete onto the mould. The casting crew is responsible for using the right concrete at the right location and layer, specifically for aesthetic designs (please see "Canoe Construction"). Quality control of the thickness of concrete is also important during the casting process. If the layers are too thin, the canoe would be weak in some areas; but if it is too thick, it could cause a weight imbalance in certain areas of the canoe, which may impact the stability of the canoe during paddling races. Therefore, thickness control gauges are placed along the canoe for convenient reference. By the end of the day, once the canoe is fully cast, it is placed in a humidifier tent for the concrete to cure with sufficient moisture, minimizing the formation of cracks in the process.
