RE: [papercreters] Papercrete & rocks

Thank you Judith, I see your point. I am not so much looking at gaining
heat from the sun, as we get more overcast weather here, but more just
having a large thermal mass to even out the day, night and different day
temperatures.

As far as things to add, we cannot get pumice here, but I do have heaps of
old boat ropes that are regularly tossed out by the local fish farmers.
These are poly ropes up to 2.5" diameter. I have started cutting these
into 4" lengths and tossing the separated fibers into the mix. Would I be
right in assume that this will give a better safety factor for roof
construction?
