Dan,
No expert here, but it seems you have too much cement, and that's the expensive part.
Several years ago I made a few blocks with 1 cement and 3 paper.
They're sitting behind the workshop, exposed to the elements, and they're still fine.
Have you experimented with different mixes?
My efforts went through a LOT of pours, and finally arrived at 1-3 or even 1-4 as a good compromise of weight and rigidity. (no sand).
Just for laughs, I tested a dried block with a 30-06 and was amazed.
My blocks were 12 inches wide, and penetration was about 5 inches - the paper absorbs energy and distributes to a much wider area.
I stopped my efforts after a few hundred blocks though - didn't have a good application for the blocks.
As I remember, it was a real pain just collecting the paper ... lol

<*>[Attachment(s) from Daniel Ford included below] Dear Papercrete Group: I'm working on a project that requires a consistent 6" h x 12" w x 52" l block. I've assembled the molds and have filled the first one to the top and will backfill the shrinkage in a day or two. (see attached photos) My question is whether or not this is the best way to pour a 6" block or should I fill it half way on the first pour? I need to make 50 of these and the sooner the blocks dry the sooner I can complete the project. For background, my mix is 1# paper, 1# portland, 1# sand, .05 # Borax. I live near Cincinnati OH and our summers are hot and humid.
