WOW, talk about overkill, a multi stage dump truck ram could probably compress wall panels. And only work a few inches of it.
I like it!
Rice hull fly ash is one of the best pozzelons available and can be mixed as 60 or more % replacement for cement be stronger and more resilient.
The Ferrocement Net discussion group Archives have some information on wood and sawdust cement composites, and I have a few files saved on my hard drives.
It has lots of merit but is another whole field of study not much different than papercrete. Fresh Saw dust and wood chips need to be aged or leached.
I believe you can use a sand clay soil and rice hull fly ash to make your own cement without
Pure pozzelon reactions are much slower than Portland cement reactions but can be ultimately stronger.

Subject: [papercreters] Horizontal Presses vs Vertical
From my understanding the advantage of a horizontal press is it
compresses from the edge of the block and therefore gives a consistent
thickness so dry stacking is possible. Does anyone know why a vertical
press could not do the same thing? I could build it horizontally but I
don't see why I need to as long as the molds and the piston are
designed to guarantee consitent thickness by compressing from the
edge or the end of the block..
I am trying to engineer a small hydraulic or air over hydraulic press.
If I get serious about a big high production press I was thinking
about rebuilding the hydraulic pump and cylinder from an old Chevy
dump truck
to use. The power would be great enough to compress a half a dozen
blocks at one time or one huge one. I was thinking that I could could
make the big blocks to sell the states for temporary road construction
barriers.
What they use now is concrete or plastic barriers {filled w/water}
which are certainly not real green and I have easy access to paper and
a hammer mill, sawdust wood chips,, fly ash and rice hulls and could
make them 1/2 the weight of the concrete and a whole lot more giving
in case of impact than the concrete.
