Drapeable fabric turns into solid concrete when it gets wet

When disaster strikes and permanent structures are leveled, as they were recently by earthquakes in Japan and New Zealand (and more distantly in Haiti), they are usually replaced in the short term by tent cities. Two engineering students thought they could do better and invented Concrete Canvas, a fabric impregnated with concrete that can turn a tent into a hardy, permanent structure in 24 hours. Just add water.
Phi Beta Iota: This has even more potential if combined with the use of cement from carbon, and non-potable water.
