anyone who has poured a wet papercrete mix ( with  cement or not)  sees 
that the wicking of water goes DOWN..keeping the base constantly wet 
for months, and often causing blowouts.

so in your  cob sandwich  the paper mess is  keeping the COB wet too, 
and wicking into it, weakening your wall.

if you are smart PRE CAST   papercrete type ( I prefer the all paper+ 
clay+lime) blocks, dried  in the sun, and install them dry between the 
cob. lessening the chancce of  soaking the cob, and or creating mold in 
the wet paper.
