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 pumasWill the block eventually dry to the 16 1/2 pounds of inert materials?Larry in NE Arizona
