[papercreters] What types of paper processing are required

Hello Group,

What types of processes paper work with papercrete? Shredded, torn, hammer milled, ...?

I was under the impression the paper had to be 'torn or pulverized', as done with a tow mixer or something like that, to get the benefit of strength of the fibers. If shredded paper works well then that opens up lots more opportunities for me (I can get shredded paper).

I also have a potential source for hammer milled paper but it looks like they worked it so hard it's now as fine as flour. Can that actually be any good for making lightweight insulating papercrete? Seems the crete would be pretty dense when dried.

I'd like to mold and pre-build the exterior papercrete panels for a geodesic dome.

This is a great group, Thanks in advance, Joel

We don't all have a tow mixer.   Marilyn

[papercreters] Re: Just a little tidbit of information

Why do you shred paper? I have build a towmixer and i can put almost anything in it(cardboard boxes and whole newspapers) without shredding it so it seems like a waist of time to shred the paper?

About the strength of the papercrete, i would be nice to see some test of pc made from different kind of paper/cardboard.

Re: [papercreters] Just a little tidbit of information]

A problem with aggregate is clogging of sprayers. Some bales of shredded paper that I bought years ago came with shredded credit cards, cd's, window envelopes, overnight envelopes (tyvec), and a few beer bottles. All of those tend to clog sprayers.

I have thrown all sorts of stuff into my mixer, including bamboo. Styrofoam has to be pre shredded or it just tends to float around on top of the mix, even with lots of agitation. The bamboo was hard to break down. It did shred into long fibers that probably helped reinforce the papercrete, but never turned into anything like pulp.

If I ever get a chain flail built (as soon as it warms up some) then I'm going to be feeding it just about everything that will go down its throat. I don't intend to put too much filler junk into any one mixer load unless it is all good insulation. Junkcrete won't be used for spraying unless I can run it through a sorter/sizer first.

RE: [papercreters] Just a little tidbit of information

I hadn't thought of it before but I will now. Thanks.

PS I like it when  a bit of the original message (or better, the entire message) is left so I can follow the thread. I don't read each and every email I get but if I see something that catches my interest I will read it.
Having the original thought helps a lot. I know there are those who have the opposite feeling about this but this is my viewpoint.
Sincerely, Judith
