Re: [papercreters] Papercrete?

To answer your question, I've used a product called Fiber 47 to make a papercrete mortar.  The Fiber 47 contains lime and portland but is an El Rey trade secret so I can't tell you what else is in it and in what proportions.   Instead of sand, perlite was used.  It was a fairly rich mix (2parts paper, 2 perlite, and 1 fiber 47)

The mortar was very strong, lightweight and bonds well to the blocks.  The only downside is that the Fiber 47 is somewhat costlier than portland and may be hard to find in some areas.

Hope this helps.

Subject: [papercreters] Papercrete?

Has anyone tried to make a strong mortar using paper fibers as a coating for
borax treated straight papier-mâché?
It seems that a one to one sand cement cellulose fiber reinforced mortar
might prove to be a kick Butt combination.
Now were talking all kinds of possibilities and combinations.
To be clearer where I'm going is sprayed papier-mâché on a form dried with
heat on the inside then shelled with a high density reinforced mortar.
Additional reinforcement added to the mortar as desired.
Something similar done on the inside after the form is removed and full
drying and or additional build up is ready. The main difference would be to
provide venting for drying or additional treating of Mache.
