Concrete Tents?

[montanadave]

Anybody seen these things in action? It's like an inflatable quonset hut fabricated from a concrete saturated fabric which, after inflation, is sprayed with water and then allowed to cure, creating a hardened shelter.

Pretty cool idea.

Cool!

Our local Kuchi do something similar with tents and mud mixed with straw, but it is not as durable as cement, and sure as hell doesn't take less than 24 hours to complete.

I've also seen it done with inflatable tents and Gunite, which is a spray on form of concrete. Again, that one takes more than 24 hours as well.
