[papercreters] Re: Mixer fixer was/Controversy

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.

But perlite isn't cheap.

It would be too much responsibility for them! So I've been getting bales of cardboard from behind Walgreen's. That's OK. You get a large amount and it's all baled for you so it's easy to handle, although heavy.

What I've been thinking of doing for expediency's sake is to make up a mix with the cellulose insulation. My reasoning is that it is already accepted and has a fire rating. If that is used along with a small amount of cement and some pumice or perlite I would have a better chance of acceptance. Since someone else will be paying for materials I could just figure it into the cost. I have spoken with the owner of an inulation company who will give me a considerable discount if I buy a large quantity. So I plan to do some sample batches to see how it goes.

I am interested to know what would be involved in getting it approved. Are we talking here about load bearing papercrete? I know there are at least 2 houses in NM built with papercrete as infill, the frame being welded steel. Code officials were very positive which is an encouragement. I am working up the initiative to start talking to them in anticipation of the summer projects.
