It's simply shredded newspaper, Portland cement and sand in somewhat variable proportions of 60/20/20. This is potentially an ideal building material because it is cheap, utilizing unwanted newspapers, magazines, cardboard and junk mail plus local sand and dirt. [....] In construction use papercrete performs like adobe because it can be made into large or small bricks. It can also be poured like cement, made into a monolithic wall, in filled between poles or studs like light-straw clay, shaped into large, reinforced panels; mortared, drilled, hammered, nailed, used as plaster, and more. [....] Papercrete does have drawbacks, and since it is still completely experimental (several houses and structures have been built in the last three years) the long term performance results aren't known. And no real insulation tests have been performed, plus papercrete blocks soak up water like a sponge (but release it again) so they must be protected from moisture and weather. [Emphasis added-PR] All that being said, it still has enormous potential as an ultra low cost building material. Or as a partial replacement of costly, commercial building products. The site, which is illustrated, doesn't mention if Papercrete can also used to make high-capacity floors for presses, but can you imagine what would happen if you were printed on damped paper and....
