We have tested it, after having a cutting torch on the petrified hessian for a count of ten, enough to cut a hole in 1/4" thick steel, there was nothing but scorch marks. By using Proper glue over your footings, when adding the petrified hessian, the wall can be sealed against termites. The mix we are using is 5 parts portland to 3 parts sharp sand, then 1 part paint to 3 parts water, mix dry and wet separately, then add enough wet to the dry to create yogurt. We have found a dipping tray works much better than painting three times, twice on the outside, once on the inside. The paint gives a waterproofing immediately, but we may be dropping it. Most of our place is being painting with whitewash, slaked line with a bit of raw linseed oil for water proofing and pest control. Since we are using hardwood logs for our reciprocal roof, we do have to worry about bug damage. My blog on building is: https://reciprocalroof.wordpress.com/ I am hoping to soon get to post the next step, but with all the rain this fall, prepping the logs has taken a long time.
Victor,
Kim haad brought up years ago the idea of Petrified Hession.This method dips burlap in concrete and attaching to the outside of your papercrete or just a pallet frame.I think this would have more fire resistance. As well as others have used certain kinds of paint in the mix.

I have done a little playing with papercrete. If the concern is fire. Why not make a higher percentage paper brick. Since paper is free. Then mortar them with a higher percentage concrete mortar. In case of a fire it would have considerable dificulty moving through the mortar. Re the termites. Would an outside and inside stucco not prevent penetration? Up nort here we don't really have that problem yet. Although we do have ants who live in wood when the ground gets too wet.

How can something be 200% by weight and 12% by volume?

Hmmm ... maybe it makes a difference how the data is presented.
Purely by volume, the portland is 12% or so.
Could someone check my reasoning?
8 cu ft total, with 1 cf portland and 3cf aggregate.
So the 50 lbs of paper must add another 4cf to make it add up to 8cf.
1cf of 8cf is 12% or so (maybe 13%).
Cost-wise, it's still about a buck a foot, if all but portland is free.
Perspective is tricky ... LOL
