I was just wondering what is it exactly that causes the shrinkage we see in so many mixes of PC?
Is ir as I assume, the paper cellulose fibers?
So even if it means not using paper, what other admixtures could be added to decrease the shrinking problem and not give up the nice tensile and insulation properties?
Some substances I have considered as "papercrete" ad-mixtures...
Sawdust, Lawn grass clippings, ground and sifted dried leaves, Pulverized bamboo, Vertiver grass (long, medium, and, or short fiber versions),
Shredded plastic bottles, broken glass bottles (may want to polish this material for beauty), Shredded plastic shopping bags, Shredded up old carpet, Shredded up old clothing, shredded old rubber tires, Mulched tree bark and or twigs, wheat straw, shredded scrap wood from regular construction, pine needles, Shredded old tar roof waste, rice hulls, peanut hulls, some sort of a human healthy dried fungus...
So what do you think? Any of that worth a shot?
