Concrete Canoe Construction with a Mortar Sprayer

Categories:

UF concrete canoe team 2013 finalsEarlier this year we spoke with Michael Stevenson, a fourth year civil engineering student at the University of Florida who plays a vital role in one of the school’s most fascinating teams. He is the construction captain of the university’s Concrete Canoe Team. This past season the University of Florida used their concrete canoes constructed using a ToolCrete Mortar Sprayer won their regional competition and went on to the ASCE National Concrete Canoe Competition (NCCC) at Lake Champlain IL. This competition is put on each year by the Association of Civil Engineers in order to give engineering students the opportunity they need to utilize the skills that they have learned in the classroom. It also provides them with experience in team building and project management that they will be able to take with them as they pursue their career after college.

The competition is hosted by the American Society of Civil Engineers (ASCE) that represents the biggest network of engineers within the United States university system. This organization provides students with a means of gaining experience outside of their college careers. The Concrete Canoe Team represents one of these outlets for students to hone and apply their skills.

After gathering information from Stevenson regarding the canoes unique building process we were able to gain knowledge on the way our sprayers were used in their construction. After constructing the canoe’s mold, from mixing to applying carbon fiber, Shotcrete is then sprayed onto the canoe until the layer is about an eighth of an inch thick. The canoes themselves are actually lighter than water (about 55 pcf for the canoe vs. about 62.4 pcf for water) due to the concrete used within its structure.

This year the team placed first at regionals, a feat one must accomplish in order to qualify for the NCCC. The canoes constructed by the university using their Mortar Sprayer by ToolCrete showed the value and competitive edge a sprayer can provide when building a concrete canoe. We wish them all the best in the years to come.
