Papercrete[Construction]
|
The book's main strength is it introduces you to a new material to buildinexpensively with. The main weakness is the fact that it is just anintroduction, and doesn't give any real solid information or advice onwhich way to build. Even given the newness of this material, I felt morefacts should have been given. The book gives you an brief overview of theways different people have used this medium, and has many pictures whereyou can judge the results of their systems.Most of the example housesbuilt using this material are not very inspiring.Mixer ideas are verygood, but overall I didn't feel the book was worth what I paid for it.

Papercrete
Papercrete is a fairly new construction material that consists of re-pulped Paper|paper fiber with portland cement or clay and/or other dirt added. When cement is added, this material is not as "green" as would be ideal, but the relatively small amount of cement is perhaps a reasonable tradeoff for what papercrete can offer. Care must be taken to utilize it properly, or you could be courting disaster. Eric Patterson and Mike McCain, who independently "invented" papercrete, (they called it "padobe" and "fibrous cement") have both contributed considerably to the machinery to make it and the ways of using it for building.The paper to be used can come from a variety of sources and is usually free. Newspaper, junk mail, magazines, books, etc. obtained from the local dump or from waste bins are all useful. Depending on the type of mixer that is used to make pulp out of it, the paper might be soaked in water beforehand or not. My first mixer used a small electric motor mounted dire!
ctly to a shaft with a couple of four inch square blades on it, rather like a milk shake maker. This shaft was suspended in a plastic 55 gallon drum where the mixing took place.It is basically a trailer made from the rear end of a car, with the part that would attach to the drive shaft sticking upward and a lawn mower blade attached to it. The blade is surrounded by a large stock watering tank where the mixing occurs. There is a baffle on the side of the tank to force the slurry back into the blade as it circulates. With this mixer (which I tow behind my Volvo station wagon) I can make three or four wheel barrows full of thick papercrete in about twenty minutes. I simply fill the tank nearly full of water, add about one wheel barrow full of dry paper, one sack of portland cement, and perhaps some sand, depending on how I plan to use the mix. Then I drive slowly around the block, back over a drain box with 1/8 inch mesh on the bottom, and dump the slurry into the box via a d!
rain hole in the bottom of the tank. After about a half hour o!

ng the excess water from the slurry, the papercrete is like soft, workable clay, but not nearly as messy.
