Coffee Table Science

Imagine a future where a piece of cloth that you lay down and  spray some water on turns into a slab of concrete! This is the magic of ‘concrete canvas’ and it is about to change some basic rules of civil engineering.

Concrete canvas is a great innovation from engineering students Will Crawford and Peter Brewin, that feels like a normal canvas but put some water on it and it hardens in a few hours to give you a robust construction.  The cloth, impregnated with concrete,  is easy to transport and just needs water and some air to complete a construction. It doesn’t need heavy equipment, good working surfaces and is not labour intensive at all. You will need lots of water, which need can be sourced from a bore well or even the sea, an air blower (if the construction is big and you are in a hurry)  and some labour to put…
