On that note, i recall reading about a British project to produce quick rise shelters. They were basically a inflatable tent with cement impregnated outer canvas.
Roll out, inflate, soak in water, and wait for it to harden before releasing the pressure.
And such a gluing agent would be cement. Concrete is really nothing more than cement mixed with sand or gravel. The farm i grew up on had a barn where the foundation was nothing more than cement and small rocks from the land. It was built up like a layer cake. One spread of cement, then a layer of rock, repeated until desired height.

It looks like the shelter use has been relegated to a secondary product vs the main use: rolls of the stuff for construction uses.

My guess is that they're not interested in dealing with small-volume customers, and so for large volumes the prices descend to a much saner price. "Look at how much your government/military/refuge 'saves' when you buy 1000 of these!"...
