In this series of blogs, we’ve previously mentioned ferrocement ships. Well, here’s another example of one of concrete’s most counter-intuitive properties – the fact that, depending on its composition, it’ll float. By messing around with aggregates it’s possible to come up with a number of different types of concrete which will remain buoyant.
It’s with this in mind that the annual concrete canoe competition was started in America. It’s a competition open to engineering and civil engineering students at American universities, and it’s been running for over 30 years, in one form or another.
According to the official concrete canoe competition…
“Students’ efforts to combine engineering excellence and hydrodynamic design to construct water-worthy canoes have culminated in an advanced form of concrete construction and racing technique known as the ‘America’s Cup of Civil Engineering.’“
We wonder what those American students could do with some pattern imprinting mats. There are a lot of videos on Youtube of the annual concrete canoe race. One thing that you’ll notice if you watch a few of them, is that although concrete canoes are remarkably buoyant – and pretty nippy – they aren’t the best looking boats out there. Those students have neglected the final stages – pattern imprinting and sealing.
