Well, I guess that I'm not very scientific about this, but one of the great things about papercrete/paper adobe is that the mix doesn't have to be exact to work. I have a 160 gallon mixer and I fill it with soaked cardboard and then fill it with water. After I tow it enough to get the cardboard fairly well cut up I add 15 shovels of clay to that. This is a standard shovel about 10 inches wide. I know there's a technichal term for this kind of shovel but it eludes me at the moment and it's really not important anyway. I tow this till everything gets pulped down to a small size and then pour it into my forms which are 2X6X8' long divided into 12"X16" partitions. I get 18 blocks from this mix if I get enough cardboard in the mixer. I usually end up a block or two short as it's hard to determine the exact amount of cardboard to put in the mix. Usually I add more after the first batch has cut up some but I rarely end up with 18 blocks. Again this doesn't matter anyway. I stake down plastic tarps and put my forms on them and let the mix drain for a few minutes while I wash out the mixer and that lets me get a good block with out too much shrinkage. With the clay soil here one needs something like this to keep from getting mired down in the mud so to speak. --- On Wed, 5/19/10, Greg House <ghunicycle@yahoo.com> wrote: wi |
