hello Ron.
i am an UG student, working on research paper on papercrete, as you wrote that you had make a small batch in your class room for scientific testing, and you use the mix design as 3:1, can you tell me that what amount of water you use for this sample.

Vickey,
I have no direct suggestions about the mix for you, but I will be doing some similar projects and have thought of a concern you may have.. I think it would be best for both of us if we used weighing to proportioning our ingredients. For people building massive structures, measuring ingredients by volume is close enough. I want to be confident that the test batches I make can be extrapolated to larger projects. You want to make sure that each batch you make is the same as the last and will be as pleasing to your customers. So we both need to make sure that our batches are reproducible. We both need the extra accuracy that weighing can give us.
I plan to use this scale:
<http://www.harborfreight.com/hand-held-digital-scale-97227.html>
It has tare capability, weighs up to 45 Lbs., is small, and is flexible.
This scale is on sale, but is less flexible and only weighs up to one kilogram.
<http://www.harborfreight.com/1000-gram-digital-scale-97920.html>
(After you prove your process, you may want a more durable scale than Harbor Freight.)

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.
