I've never used it, but I admit I'm learning since the posting. lol.
I doubt if this answers the specific questions posed, but it probably
will answer many of the unasked questions about it from others in the
group. These first 2 links come from the self proclaimed inventor.
(of course I've found other references dating back to Stanislas Sorel
in 1867, so I don't know if I recognize this dude as the inventor.)
The cool thing about this link is where it comes from... TASMANIA...
that alone makes the link cool. hehehe

I'm trying to figure out how much of the MgO will leach out of
papercrete as it drains. If too much leaches out it won't be a good
thing to use regardless of cost.
It looks like MgO also plays well with other stuff, e.g. pozzolans,
like fly ash.
