I completed a test pour of a modular papercrete block that would be
laid up with standard coursing, could contain elec conduit and
rebar..... it was time consumming. I built the form out of plywood,
coated it very heavily with sealer, and it probably won't be able to be
used again due to warpage.
Here's some pics:

I experienced quite a bit of shrinkage vertically. In rough numbers
about 10%, and the mix was very stiff and contained quite a bit of sand
and portland. Total dry mix weight including portland, paper, sand,
etc... was about 9.5 pounds. Block size 8"x8"x16"
Its a little clunky I had a few gaps in the pour, but generally I'm
satisfied with the end result.
Welcome comments.... or tell me I'm crazy...... Duane
