So you could put the pulp in a cement mixer truck, add the water/cement, mix and pour or pump like concrete. If you are building a house you could make the forms 4 feet high all around (like I did, no breaks) and go right around up with the walls. I don't know how far a whole mixer load would go but it sure would take a lot of the "fun" out of building a papercrete house.
They who can give up essential liberty to obtain a little temporary safety, deserve neither liberty nor safety.

What I was envisioning is a system that would pump the pulp from a tanker, and another pump that would inject premixed cement/water slurry into the hose. It would take some calibration to get the right mix, and there would be some sort of mixing action in the nozzle perhaps. Maybe something like the spiral nozzle used on some epoxy tubes.
That is about as far as I got, since I don't have a source of pulp other than my mixers. A system like this would require forms large enough to handle a whole load of pulp at one time, of course. It could probably be adapted for spraying, too.

Spaceman --
Really interesting what you say - I am following for almost one year the list, intending in the fall to start experimenting, but never heard about papercrete made directly from cement and paper pulp. Can you please be more specific on how you see this happening? I can get quite easily recycled paper pulp, in different consistencies (i.e. with more or less water in it).
Thank you,
Ion

I think that the mechanical pulp should also be healthier than pulp processed with chlorine, which is extremely toxic. When I was in high school my family lived within smelling distance of a pulp mill. It's too bad I didn't know about papercrete back then. A few tanker truckloads of pulp could make a house almost overnight with the right formwork in place. It should be easy to rig up a pump system that also injects cement slurry so you could go straight from the tanker into the form in one easy shot. If there was a pulp mill within driving distance I would probably do papercrete almost every day. : )

I believe the virgin pulp is a little stronger than recycled. Chlorine mills have better pulp than thermo mechanical mills. Even though the latter is way more environmentally friendly. I don't think getting paper is a problem for most people anyway. I live a cross the road from the recycle depot. I can help them out when it starts blow away with are normal 100km winds.
