Hi all. Bill here. Brand new to coblist (or any list
for that matter).
We're breaking ground this spring for our cob home
(Northern New England) and are trying to get the perfect
mix.
Has anyone added recycled gypsum board (Pulverized) to
their cob mix to stabilize it? The guy with the "cast
earth" is kind of cloak and dagger about the whole idea,
but claims that it slices, dices, chops, folds your
laundry, and stops hair loss. Unfortunately he's a
little out of my budget range.
Also, I made a plaster mix of 1 part lime/1 part rice
flour/10 parts earth -our dirt is about 20% clay- and a
good amount of goat hair (read:free). Our scientific
compression test: (my girlfriend rides piggyback while I
stand on a dried 5x5x3 cob - combined weight about 260
lbs) no breakage. The stuff won't break. It took
everything I had to twist off a chunk. I think we've
found our interior plaster. We'll probably use milk
paints to make it pretty.
My biggest concern is the low r-value of cob. Our (load
bearing) walls will be starting at 36 inches thick at
the base, tapering to about 26 inches at the rafters.
Helpers welcome this spring, talk to you later.
