Thats the equivalent of nearly 2,000 toilet flushes!

Why Recycle Paper?

Protects and conserves our clean airManufacturing 1 ton of paper from virgin wood pulp creates an additional 60 pounds of air pollution.

INTRODUCTIONy Paper concrete construction involves using waste paper for

affordable, sustainable housing. y 45 percent of discarded paper is recycled annually, 55 percent or 48 million tons of paper is thrown away or goes into the landfills in USA y It takes about seventeen trees to make a ton of paper. y 50-80 percent waste paper contain using in concrete

WHAT IS PAPERCREATEy y y y y

he name seems with a mix of paper and concrete, hence paper-crete. PAPERCRETE is a tricky term. It is a fairly new construction material that consists of repulped paper fibre with Portland cement or clay . Lime dust may be used as a more carbon neutral alternative to Portland cement. It is more accurately, when the Portland cement is used in mix.

Cont.y This type of material is considered environmental friendly

material. y It was discovered by Eric Patterson and Mike McCain. y There are no harmful by-products or excessive energy use in the production of papercrete.

ADVANDAGEy Saves landfill space. y Keeps paper processing & printing chemicals out of the water y y

table. Saves trees and other construction resources, which would have been used in place of papercrete for walls and roof. Saves additional trees and other construction resources, which would have been used to "build out" or finish the interior and exterior of the structure. Saves a significant amount of energy during the lifetime of the structure. Provides new construction jobs. Provides low-cost, sustainable housing.

Disadvantegesy Safety factors. There are many variations in creating

papercrete that no one know which one is the best. y There is no way to get a loan using it as collateral y Papercrete is still not classified as anything and therefore it is hard to find a good creditor willing to give you a loan and if one finds one the rates might be higher.

Making Papercrete First paper is gotten. The paper can be gotten form newspaper, junk, mail. Magazines, and books. The paper may be soaked into water A mixer is used to mix the material with Portland Cement and maybe with other additives.

TYPES OF PAPERCRETE Fibrous concrete or fibercrete, Fidobe, Padobe Paperpulp

FIBROUS CONCRETE y It is use with fibrous material such as paper with Portland cement and water. PADODE y It is a mix of paper, water, and earth with clay. FIDOBE y It is like padobe, but uses fibrous materials. PAPERPULB y It may be added to clay soils where sand is not available. y It helps to minimize cracking when the material dries.

Propertiesy Dried Concrete has very low strength y Papercrete provides good insulation y R-value is about 2.0 and 3.0 per inch y Lightweight y Its mold resistant material and can be used as a sound-

proofing material. y Compressive strength of 140-160 lb/sq in

Continuedy It is dimensionally very stable y Does not support flames and will smolder for days. y The more cement and mineral material is used the more fire

proof it becomes. y Resist rodent and insect infestation

forms. The 2' x 4' forms should be built of 2 inch by 4inch (5 x 10 centimeter) depth. If you make larger, thicker panels, they will take longer to dry and you may need help to get them up on the roof. To keep the papercrete clean and help drain out the water, put a sheet of shade cloth on the ground under the form. Strong panels are made by filling the form up to within a half-inch from the top and then spreading a piece of chicken wire over the mix. Pour the remaining half inch of mix, smooth out the surface with a trowel and should be able to handle the panel in about four days. It will probably take the panel two weeks or so to completely dry.

Cont..y For the greatest strength, roof panels are installed over offset

chicken wire and two thin layers of papercrete. y First a sheet of one-inch chicken wire is tightly stretched over the ceiling joists of the structure a y A second layer of one-inch chicken wire is offset 1/2 inch from the first and installed the same way. y Then a thin layer of papercrete is spread on the chicken wire and allowed to dry to form a strong base for the roof panel.

WATERPROOFINGy Long available for industrial applications, crystalline waterproofing is now y y y

used in residential applications. It consists of a dry powder compound of Portland cement, very fine treated silica sand, and proprietary chemicals. Combining the product with water and applying it to the surface of concrete results in a catalytic reaction. This seals the concrete against the penetration of water or liquids from all directions. If it will hold water without leaking, it should prevent water penetration. If the sun is very strong, and there were no problems with it. It's tough, flexible and absolutely waterproof. The total load at the base of the wall would be about 550 pounds per square foot. Since papercrete is variously rated at well above 100 pounds per square inch, there is a very wide margin for wet snow or any other additional roof load.

PAPERCRETE BLOCKy y y y y y

It is not used as a load-bearing wall where building codes apply; however, its strength and durability high. In model structures is proven and homes and small commercial buildings are being constructed. Papercrete block use a mixture of water, cement with cellulose fibre, which is usually acquired from recycled newspaper, lottery tickets and phone books. The mixture has the appearance and texture of oatmeal and is poured into forms and dried in the sun, much like the process for making adobe. Papercrete is remarkable in that it takes on the strengths of wood and concrete, but is missing the weaknesses of either. Unlike wood, it will not crack or burn. Unlike concrete, it will not fracture. Concrete and wood are not known for their isolative qualities, however, papercrete takes on isolative qualities that make it superior to many conventional insulating materials. papercrete blocks are lightweight, less than a third the weight of a comparably-sized adobe brick. Papercrete is mild resistant, has utility as a sound-proofing material and is bullet-proof.

screwed into the papercrete opening. The gaps can be trimmed conventionally and/or filled with papercrete and adding a small amount of Plaster of Paris to papercrete where it comes into contact with wood. If wood or metal frames have to be installed, they can be screwed directly into the papercrete. At a construction of unsupported papercrete block walls, between floor-toceiling windows, angle-screwed to the window frames. The frames themselves were independently anchored to the floor and to the roof plate. This stabilized the short walls extremely well. Any gaps are filled with papercrete and the inside surface of the wall opening (not covered by the frame) can be surfaced with papercrete. The glass can simply be embedded in the papercrete. Papercrete doesn't expand or contract , even when wet or frozen, so sheets of glass or glass block can be embedded in and trimmed with papercrete without fearing
