[Cob] hybrid systems(cobwood)

[Kim West]

What are you referring to as rock dust? We used two different kinds of
"sand" in our cob. The first looked like sand but had sharp little pieces of
crushed rock in it. It cut our feet so badly that I had to wrap them in duct
tape by the third or fourth day of stomping cob else give up and admit
defeat. The second load we got was from the dirt hauler's land and it was
all natural--just the way it came from the earth. Never had a prob with it
and it seems to have done quite well. Will know for sure once the house is
finished next year.

He said that he didn't really have enough experience with cob to be able to
comment too much on it. He said that it did look promising but that only
time would tell.

here to begin cob as we have freezing weather already. Come April we'll be
ready to have cobwood workshops and everyone can learn together.

sense. Besides tourism, our only real industries are lumber and rock. There
are always wood scraps available for free/cheap and I have had good success
so far using rock dust in the place of sand. The price difference alone
between rock dust ($9.50 a ton) and sand ($50.00 a ton) make rock dust the
obvious choice as an aggregate in cob.
