Many of those "peanuts" will dissolve in water, there made with corn starch. They also compress easily so will not carry a load. So you have to make sure you're getting the tough ones.

Has this fellow tested the Paracrete for off-gassing? Has it been tested for off-gassing during a fire? I would think that the external facade of his slabs would melt/ dissolve under the intense heat of a California fire, being that they're paint and styrofoam specks. That would leave the fire to burn/ melt the next level, etc. You might have a 'scaffold' of portland cement left after a fire. But you'd have probably choked to death from the toxins in the meanwhile. Just guessing. I guess you could call me a Purist. (Unless I'm wrong about the fireproof qualities of cob? Don't we make ovens out of it?)
