I would think that uncompressed papercrete (the kind poured from a tow cart) would never be considered a solid (like concrete) because it would squish nearly flat long before it breaks. Maybe they would measure this squish.
As for measuring the pressure - it's easy enough to put a pressure gage on the jack and know exactly what pressure is being applied.

What I'm wondering (and it's probably a very simpe thing) is how do you measure the psi? I can see putting a cylinder of cured papercrete into a jack or something and increasing pressure until it fails ..... but how do you measure how much pressure was applied?
