[Cob] cob as mortar for cordwood building

[Amanda Peck]

Asphalt Emulsion sticks to almost anything--even AOL CD's.  Ms Taylor 
included a papercrete/AE one in an order once.  I wouldn't think that poly 
bags would be a challenge after that!

Evans and Roy did some cob/cordwood experimentation together.  Not sure what 
the result was.

The trickiest thing might be to tuck point a new layer of earthen plaster or 
lime mix or whatever around the logs--still want the logs to stick out a 
little bit, want the straw in the cob proper to be covered, want a nice 
smooth surface that is at least semi-waterproof.

Pack McKibben, Charmaine Taylor and Mary Lou McFarland are doing some 
thinking about cob and cordwood (here's McFarland's thought):

Jack Henstridge is one of the "grand-daddies"  of cordwood building and his 
recipe for mortar mix is as follows:  1 measure of portland cement, 2 
measures of sawdust, 3 measures of sand and gravel.  Perhaps it would work 
to replace the portland with hydrated lime, and use the sand and clay 
instead of the sand and gravel.  Just a thought.
