So you don't put any cement or clay in your mix? What are you building? I made a bunch of blocks one time and forgot to put cement in. They were so nice and fluffy and light. I eventually used them in a slip form wall but would not use them exclusively. And I would think that with your rainfall they would disintegrate quickly.
It would be interesting to do a slip form building with just the paper and water then use the int. and ext plaster to provide the water resistance and some strength.
I have just put down a paperadobe subfloor. I think I started it about 2 weeks ago and finished it yesterday. My truck was broken down for a while which set me back. Well anyway, it is taking a long time to harden up. I know it takes a lot longer for clay than cement but I'm not used to having to wait this long. Even the part that is 2 weeks old is still squishy, although it seems to be improving. I will be taking a workshop with Carole Crews in Taos next month on plaster and mud floors so want to be ready to hit the ground running when I get back.

Subject: Re: [papercreters] Rookie mixer?
Use what is available as papercrete is so versatile.
I use my trusty cement mixer sitting alongside an old bath tub. While I'm
working on other projects in the back yard I chuck a heap of paper and
water in the mixer and just let it rotate. I use about a tight 2" stack
of catalogues to a mixer of water. This allows the fibres to be teased
apart rather than being cut or broken and gives an amasingly strong end
product. As the paper is a very wet mix the mixer takes very little power
to keep it turning. I find the wetter the mix the better the fibre
separation into pulp.
I just pour each mix into the bathtub as it's ready. The pulp settles to
the lower half of the water. As the pulp is poured into one end of the
bath the excess water flows out the other end and can be recycled into the
next mix. The bath effectively acts as a slow version of a thicknesser in
a production factory. The resulting pulp mix is scooped out by the
bucketfull as required depending on the project at hand. It is handy to
have a continual supply of pulp for my constant experimenting. Just scoop
and use.
No other aditives are required to make a solid product. As paper is
basicaly wood fibres and clay the finished product comes out as hard as
wood and more rigid than LDF. I pour into molds to make bricks and
decorative panels for interior use and areas protected from rain. I gave
up trying to find a PC mix that will last well in the rain as the 200+
rain days per year we have seems to be just to wet for PC. It pays to
mention however that not adding sand or cement allows more shrinkage,
hence the precast nature of my work.
