Re: [papercreters] re: pole barn (house) construction with PC infill

I looked at nwjoinery.com but didn't see the salt box house plan. Maybe
it is in the downloadable pdf.

If you are using wooden posts, wood has a good R value. You would need
to be able to seal the joint between papercrete and wood.

If I were infilling between posts I would use a slip form and not bother
with blocks. Usually a plaster topcoat is applied over blocks (as you
plan to do) and they are concealed anyway. Slip-forming is a big labor
saver over blocks. Mix, dump or pump, and you're done. With blocks you
mix, mold, turn for drying, move and stack, mix mortar, place the blocks
with mortar. Every step is added labor. You can do 1' lifts with
slip-forms, giving it a little set time between lifts. To get enough dry
time you probably needed to start months ago. The good news is that
freezing doesn't seem to affect my papercrete, the bad news is that wet
papercrete isn't very good insulation.

I was camping in MT and on the 4th of July I had to break ice to get a
morning cup of tea. Yeah, it gets cold there :)
