I have found that adding sand and light aggregate does not work all that well in the tow mixer. True, it does allow the paper to pulp, but the heavy stuff is overly proportionate in the bottom of the mix and the top does not have nearly as much of said sand and light aggregate. I use heavy cardboard and quit using cement and sand/aggragate as by allowing the water to drain out of the block forms and then packing it well with a 2X4 tamper I get a very solid block with very little shrinkage. They actually seem to be harder than the blocks I made with cement and aggregate. AND, they are very light and easy to handle. I'm still skeptical about the insulative qualities being the same for an all paper block vs. a 50/50 paper to aggregate mix. The half of the mix that is sand/aggregate can not have the same R value as paper so how can the resulting block/pour be higher in R value than straight paper/cardboard? --- On Sun, 7/1/12, spaceman <Spaceman@starship-enterprises.net> wrote:
