I don't recommend papercrete.
However, padobe can work extremely well.
I have used pulped paper instead of sawdust using the aprovecho process described in this video. Works great.

I shaped mine into one big cylinder. (rammed the wet paper and clay into a cylindrical mold) Then allowed it to dry for several weeks before GENTLY firing it by slowly starting a small fire and very gradually building up the temperature.
The paper still burns out ... as spaceman suggested it will if papercrete is used. However, using enough clay leaves behind a ceramic matrix filled with tiny holes where the paper pulp burned away. Excellent firebrick insulation.
Give it a try.

Has anyone used papercrete to fill between chimney's in a rocket stove? I was going to experiment with small Stoves and see how well it would do vs the perlite etc. Any response would be appreciated
