[Cob] straw in cob or concrete?

[Ocean Liff-Anderson]

Have you ever gotten concrete on your hands?  It is highly caustic,  
dissolving all carbon life-forms...so straw doesn't have a chance!   
Concrete guys will throw in bags of loose poly-fibers (plastic) which  
are supposed to prevent cracking in slabs...

But rebar even doesn't hold out forever, because concrete acts as a  
wick, drawing whatever moisture hits it straight in - rusting the  
rebar and causing collapses of bridges, etc...Now they coat the rebar  
with epoxy or plastic, then pour the concrete over it.
