No really good reason based on your "easy to cut" logic. However,
after the wall is in place, I'll be able to fish romex vertically
every 8" without cutting into the wall. Since I'll have these wiring
locations figured out ahead of time then this probably is minor.
Honestly, I just wanted to see if a totally flexible modular unit
could be created that could accomodate building systems like elec and
plumbing without cutting.
I did tamp the block, but obviously not well enough. I made the pour
late at nite and the mosquitos were so thick it was tough to work.
I'll probably shorten the height of the block so that vertical shrink
is less an issue, there was almost zero longitudinal shrink.
One thing I have found is that fans dry the blocks much faster than
just sitting in the sun. Somewhere in the neighborhood as twice as
fast.

when the dry blocks are so easy to cut through with a chainsaw or
sawzall. I make my blocks by the "brownie" method. I pour into a form
30" x 12' and cut them with a lawn edger when they are still wet but
set up enough to hold their shape. I lay them up like bricks but make
the mortar with slightly more paper and leave out the pumice, or sand
in your case. I find this rather simple. I have cut the blocks with
the sawzall with a long deeply serrated blade. You're not crazy. Hey
if you are crazy then that means I'm crazy too and we can't have
that! Judith

coated it very heavily with sealer, and it probably won't be able to
be used again due to warpage.Here's some pics:
http://www.domovitae.com/fcrete/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
