Jeff,
I agree the typical papercrete mix would be too watery. But I suspect --
* separate pulper to produce the pulp.
* drain pulp and extract much of the water.
* Mix the pulp, sand, crete in a std mixer to proper consistency.
* drop into the former and compress.
No it will not be a Michael Sands lite block, but a heavier block still suitable for construction.
