Way back years ago someone posted that they had used papercrete blocks to build a fire pit, and after several fires the bricks were black but not degraded. I don't remember seeing a follow up report later.
I would think that if pc is used in an area without really high temperatures then no problem for sure. In really high temperatures I would expect the paper fibers to char and leave the cement matrix behind, which is good insulation like foamed concrete. As Kim said, high cement content would be recommended.

Hi! I was wondering if anyone has any experience in using papercrete to insulate chimneys? I'm planning to make a rocket mass heater, and I see most people use perlite, but perlite is very expensive here, so I was thinking using papercrete instead – ideas anyone?
