RE: [papercreters] Thought

In my experience the longer the block dries the lighter it will get. I recently moved a pile of blocks I had made about a year (or maybe longer) ago. They were incredibly light, except for the ones I made when I first started out. They were made with more sand rather than pumice and cement and were very heavy after 2 years. I think it's really good that you had the idea to weigh the materials and the resulting blocks.

Subject: [papercreters] Thought

Perhaps a stupid question, but an interesting one:
 
If you use X amount in inert materials (Paper, Concrete and sand) and Y amount of water. Would the dried papercreate equal the value of the inert materials?
 
During my introduction to papercreate, I built a 1' X 2' X 5" block, and after about two weeks of drying time the block weighs 21 lb. The total weight of the inert materials is 16 1/2 lbs. and 7 gallons of water. This than leaves 4 1/2 lbs of what?
 
7.0   gallons of water
4.5   pounds of paper
7.5   pounds of Portland cement
4.5   pounds of pumas
Will the block eventually dry to the 16 1/2 pounds of inert materials?
