[Cob] Cob/cordwood hybrid--plaster question...

[Amanda Peck]

Concrete is what nearly everybody used 20 years ago, and the house is still 
fine.  They are still living in it very happily.

Building it today, I would want to examine other alternatives to pure 
concrete.  But I know a couple of people who believe that 5% portland cement 
is needed for cob.  Especially down towards ground level.

(isn't breath was the noun form?)

I wouldn't want to use a cement based product... it won't breath.   Worse it 
will wick water to the wood.  I think 'cobwood' with an  earthen or lime 
plaster would do marvelously.
