Hi Kurt, welcome to the group. There are knowledgeable folks here who are always friendly and helpful. A great place for you to start would be the archives, especially the early messages when the group was really busy. After you work your way through those posts, then if you still have questions you'll probably get an answer just by asking. Don't forget to look at the files and photos at the group page.
One thing - in your post you mention concrete. Papercrete is not concrete, nor does it act like concrete. It is more like a wood product. Fire resistance is accomplished by adding borax or boric acid which also is an insect repellant.
The simplest papercrete is paper pulp with portland cement added. Many people also add sand, clay, various other minerals like perlite or vermiculite. The more minerals you add the heavier your pc will be, and the lower the insulation value. There is a wide variety of formulas depending on the final purpose of the pc.
In a tropical country you probably need good boots and a wide hat, meaning a good foundation that keeps the papercrete up above splash, and a roof overhang to protect your walls. Unsealed papercrete absorbs water like a sponge, then dries out and becomes hard again. In a rain forest it may never dry out, so a seal on the outside where it is exposed to moisture may be necessary.

Hi! I'm Kurt, I'm from the Philippines. I've just come across with papercrete just recently, like last month. This new technology for construction is very interesting and it also helps in the advancement of green technology. I'm currently running a company that is into scrap paper trading. Most of our papers are shipped to paper mills for paper recycling. Using paper fibers as an ingredient for making concrete is a new technology here in the philippines. I'd like to ask if you guys could give guidelines and tips in the production of papercrete. We are still in the research stage right now, and any information that you guys could give will of great help and really much appreciated. Any additional info based on your experiences in constructing and the making of paper mash, the mixture, the ingredients for binding the concrete, the percentage of mixture, and the form will be really much appreciated. What additives are placed to make papercrete fire-resistant and will it stand in a tropical country like ours? Hope to hear feedback from you guys. Thanks. ------------------------------------ Yahoo!
