There is a 6 part site making something very similar to what you are talking about below, but instead of paper pulp, he uses a polymer fiber, I asked him if he thought paper pulp could be used instead of the polymer fiber and he said he didn't know why not. This is the site and a discription of his mix.

First create your water mixture of 1 part J-40. Acryl 60 by Thoro Products to 3 parts water, then add 1 part of this water mixture to 3 parts styrofoam to 1 part mortar cement. (It doesn't matter what you use to measure; just so there are three "scoops" of styrofoam to one "scoop" of cement and 1 scoop of the water mixture).

Hello all,
It's the shredded paper that is hard to get. Waste paper and cardboard can be found most anywhere for free. I'd like to use papercrete for infill installation between inner and outer concrete walls - like a double dome. I'd also like to ensure the inner and outer walls are not connected together with steel or anything that will conduct the cold/hot except around windows and doors.
For fun try making a sample of light weight concrete with perlite and cement to use as infill or? . Start with 1 pound perlite and 2 pounds cement and 2 1/2 pounds water. This makes a really soild block that has very little water runoff and dries fast. It looks like porus stucco. With 3 pound of cement you can float the surface.
