Ron- Thank you very much. That is what I needed. A good place to start so I could work the percentages from there.

Vickey,Our science class just got done making a model of a house to test for efficiency for a science fair. We used a 5 gal bucket to mix our batches. If your final PC mix is going outside I would suggest sticking with a pound of paper and then adjust your other ingredients as percents. For example for outside I would not go below 2:1 ratio of paper to cement. Make it higher if what you are making needs more strength than insulative qualities like 1.7 to 1. We mixed these batches in the classroom with little mess so it is not huge but you could even do a 2 pounds of paper batch. Keep the ratio simple by using 1 pound of paper then just like a cookie recipe if you double it (the paper) all the other ingredients will double as well.Since we were making a model we used a ratio of 3:1 because it will never have to withstand outside issues. So in our instance 3:1 was 1 pound of paper to 1/3 pound of cement or 5.3 ounces. Experiment and see what happens. Of course you may include sand and or ???Ron

Subject: [papercreters] Re: looking for small batch recipe help
Let's try this again in english.....since it appears I did not make it clear what I was asking for help with.
What I am looking for is approximate quantities to fit in the 5 gallon bucket. I intend to do some experiments but was hoping someone had some basic ideas of what quantities I needed to make just a five gallon bucket of mix not a 200 gallon tow behind mixer.
I know all about hypertufa, using peat moss. Not what I am trying to do here. I want to experiment with papercrete. I know people are using it for sculptures and such. This should not be so hard to figure out, but since I have never done any papercrete I thought maybe someone could give me the basics for a five gallon bucket so I don't end up with way more or less than I will need to make the test batches with.
Thanks again for any help.

If you make a batch of paper pulp, you can dvide it up and add varying amounts of cement, sand, and whatever else you have lying about you need to dispose of. Mould one item from each subbatch and see what ends up satisfactory to you.

Have found several recipes in the messages I have searched, but not sure which is suitable for which purposes. I know the stepping stones need to be stronger than the wall plaques but would appreciate any suggestions from those who have actually made papercrete.
