BUILDING WITH PAPERCRETE AND PAPER ADOBE PDF - Papercrete is the ultimate building material for preppers, homesteaders, and off grid living enthusiasts. Not only is the building material incredibly Toggle navigation. Portland cement is partially replace by the papercrete which is considered as new composite material prepared by the waste papers. This papercrete not only reduce the amount the impacts of paper sludge made papercrete on the environment and its preparation. Paper Sludge, Cement, Environment Pollution, Papercrete Authors: 1. Papercrete is a building material composed of “re-pulped” paper fiber with clay or Portland cement, or other soil added. The material was first patented during the 1920s and experienced a revival during the late 1980s. Many preppers disagree on the environmentally friendly nature of paper concrete.
Papercrete is a construction material which consists of re-pulped paper fiber with Portland cement or clay and/or other soil added. First patented in 1928, it was revived during the 1980s. Although perceived as an environmentally friendly material due to the significant recycled content, this is offset by the presence of cement. The material lacks standardisation, and proper use therefore requires care and experience. Eric Patterson and Mike McCain, who have been credited with independently 'inventing' papercrete (they called it 'padobe' and 'fibrous cement'), have both contributed considerably to research into machinery to make it and ways of using it for building.[citation needed]
Manufacture[edit]
The paper to be used can come from a variety of sources, including newspaper, junk mail, magazines, books. A mixer is used to pulp the mix. Depending on the type of mixer, the paper may be soaked in water beforehand.
Standardization and commercial acceptance[edit]
As of 2007, papercrete lacks approval from the International Code Council. This limits its range of use within the city limits of most incorporated United States cities where building codes apply. It is not used as a load-bearing wall where building codes apply. However, its strength in model structures has been proven, and homes and small commercial buildings are being constructed. There is little or no evidence of its long-term durability at present.
In these small building projects, papercrete is being used as an in-fill wall in conjunction with structural steelbeams or other load-bearing elements.
Papercrete gets its name from the fact that most formulas use a mixture of water and cement with cellulose fiber. The fiber 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.
Dried papercrete has very low strength, but fails by slow compression (due to the large air content and hence compressibility) rather than in a brittle manner. Concrete and wood (though dry soft wood can be as high as R-2 per inch, high moisture content reduces this value markedly.) are not known for their insulating qualities; however, papercrete also provides good insulation.
Papercrete's R-value is reported to be within 2.0 and 3.0 per inch (2.54 cm); papercrete walls are typically 10 to 12 inches thick (about 25–30 cm). Unlike concrete or adobe, papercrete blocks are lightweight, less than a third of the weight of a comparably-sized adobe brick. Papercrete is mold resistant and has utility as a sound-proofing material.
Research tests into papercrete have been carried out by Barry Fuller in Arizona and Zach Rabon in Texas. Fuller directs government-funded research on papercrete through the Arizona State UniversityIra A. Fulton School of Engineering. He is also head of a subcommittee for the American Society for Testing and Materials, and it is his goal to set standards that will lead to acceptance of the product within the architectural community and commercialization of the product, especially for affordable housing.
Structural tests have been completed on several papercrete formulas and Fuller claims the compressive strength of papercrete to be in the 140-160 psi range (0.96 - 1.1 MPa), while others like Kelly Hart claim 260 psi (1.7 MPa).[1] For comparison, the compressive strength of concrete ranges from 15 MPa to over 70 MPa (2200 - 10000 psi) depending on the application. A more useful measure of papercrete's properties is its stiffness - i.e. the extent to which it compresses under load. Its stiffness is many times less than that of concrete, but sufficient for the support of roof loads in some low-height buildings.[citation needed]
Dried, ready-to-use papercrete has a rough surface. This increases its surface area and provides a very strong bond from one block to the next.
Papercrete has also been tested for its tensile strength. Fuller notes that a papercrete block is the equivalent of hundred of pages of paper - almost like a catalog. Papercrete has very good shear strength as a block. Lateral load involves sideways force - the wind load on the entire area of an outside wall for example. Because papercrete walls are usually a minimum of twelve inches thick, and usually pinned with rebar, they may be strong laterally.
Zach Rabon founded Mason Greenstar in Mason, Texas for the purpose of producing and selling a commercially viable papercrete block. His product, Blox Building System, is at present the only mass-produced commercial papercrete block in the market. He has built several residential structures with it.
The Mason Greenstar block had its genesis in a journey Rabon's father, Kent Rabon, made to Marathon, Texas. The elder Rabon made the acquaintance of Clyde T. Curry, the proprietor of Eve's Garden Organic Bed & Breakfast and Ecology Resource Center.
What Is Papercrete
Mr. Curry was an early proponent of papercrete and benefited from the lack of building regulations in the small mountain community of Marathon. Curry built four of the rooms at the bed and breakfast either partially or entirely out of papercrete and is in the process of building two more, in addition to a library and reception area, entirely out of papercrete.
Papercrete's ready moldability provides considerable flexibility in the designed shape of structures. Domed ceilings/roofs may be commonly constructed with this material.
Along with Fuller's work at Arizona State University, Curry's establishment has become a resource center for people interested in papercrete, and workshops are intermittently held there.
The Rabons had prior experience as homebuilders and are owners of a ready-mix cement plant in Mason. They have invested in research and testing on their product for several years. However, they consider their product a proprietary formula. They have filed for a separate patent even though a patent for papercrete had already been filed in 1928. The block developed by Mason Greenstar is known for its uniform shrinkage (all papercrete blocks go through a lengthy dry-time that involves some shrinkage), giving it a sharper edge.

Fuller has remarked that in tests he has performed on the Rabon block, it has outperformed other formulas.
Papercrete is claimed to have benefit of being a project that involves little cost to start. The materials are claimed to be cheap and widely available. Rapidshare files rar. Machinery suitable for small-scale construction is simple to design and construct.
When properly mixed and dried, the papercrete wall can be left exposed to the elements. In its natural state, it is a grey, fibrous-looking wall. For a more conventional look, stucco can be applied directly to it.

Papercrete Planters
Since 2006 a small company based in England, Econovate Ltd has developed, with the support of Cambridge and Bath University, a papercrete formula and production process for breeze blocks to be accepted by British Standard and a green certification for Europe. This new mixture of papercrete is to withstand the wet and harsh English weather. As of 2009 Econovate was in the process of developing this product and reaching manufacturing trials stage. A patent was filed in 2011 for the production process of breeze blocks with this material. De design of machinery was necessary to achieve a successful scale up of production. In January 2013 Econovate became fully funded to set up its first demonstration plant capable of producing up to 1.5m blocks a year which expected to achieve certification by October 2015. The company has tested the product at UKAS register testing houses for 18 rigours test such as fire, strength, moisture movement, acoustics, thermal, durability and others toward the product certification. This certification by LABC was achieved in dec 2015. The company was also in the process of achieving ISO 9001, 14001, 18001 and BS eN 6001 (responsible sourcing). Its ISO 9001 certification was achieved in October 2015. Econovate with its product Econoblok is producing a breeze blokc, UK standard size (440mmx215mmx100mm) with 5Mpa and another with 7Mpa. The difference between the two will be the amount of fibre within the mixture and this can range between 55% to 79%. The more strength the less fibre thus less thermal. After gaining Certification the company has increased production and the product is called 'econoblok®'. Initial commercialization will be in the UK until the production process is fully tested and ready for up scaling to a full size plant. From January 2017 the company will start preparing for the full size plant of 5-6 million block production, this will be based in the UK. Econovate plans to expand to other region of the world where some basic recycling system exist.
Compressive test on papercrete block reveals that papercreate can withstand load up to its 30% axial compressive strain.
Do it yourself[edit]
Papercrete is rapidly gaining a groundswell of support among 'do it yourself' builders.[citation needed] It is claimed to be a very attractive building material due to its very low cost, light weight, and high performance.[citation needed] Many owner/builders are contributing to furthering the technology and sharing their experiences over the internet through resources such as 'Papercreters'.

Building With Papercrete Pdf Free Free
People who are truly earth conscious tend to live off the grid. They make every effort to conserve energy, make less impact on the earth, and use materials that are both readily available and sustainable in their building projects. No discussion on earth friendly buildings would be complete without talking about papercrete and how it is used to build homes. This article focuses on papercrete and how it is used, plus some of the advantages of a papercrete home.
What Is Papercrete?
Papercrete is made from recycled paper with a small amount of cement and sand added. The ratio is 60/20/20. The paper/concrete/sand mixture is stirred in a large barrel, much like a blender, until all paper is shredded and evenly mixed with the concrete and sand. Papercrete can be mortared, drilled, hammered, nailed, used as plaster and as an infill between poles or studs. Recently, some people made the mixture without cement, and created Fidobe or Paper Adobe. These products are dense building logs used in construction.
While researching, I found a gentleman that had made a mixer out of an old 55 gallon drum, which was mounted on an old car axle. A unique gearing system attached to an old lawn mower blade did the mixing. He would hook this contraption behind his car, take a slow drive around the block, and have perfect papercrete.
How Is It Applied?
Papercrete is handled much like adobe. It can be made in smaller bricks or can be used much as cement is, and poured into a monolithic wall. If papercrete is poured in a monolithic wall, the density on the bottom will be much greater than on the top. The papercrete will be cut off from the air, causing drying issues. This can cause pockets, creases and voids in the wall. Papercrete will also shrink 30% in height when drying. It stands to reason that building using the slip form method is the safest bet.
One method of construction is the wattle and daub technique. In this construction, a wall is woven using poles and reeds, and then the papercrete is applied. This method has been in buildings dating back to primitive times.
Another technique used is the slipform method. In this method, the papercrete is poured into the forms creating the exterior walls. Forms are placed one on top of the other until the correct height is reached. The papercrete slurry is used to fill joints and reinforce the blocks. This type of construction is very strong, and is used in high rise buildings, silos, and multi-story buildings. Using this technique for building a papercrete house is a good choice.
Finishing Papercrete
Papercrete has the disadvantage of not being waterproof, and extra care must be taken during construction to insure that the site is completely waterproof on the exterior. The exterior can be finished with one layer (1/2') of homemade stucco, the mix being Portland cement, slick lime, masonry sand, and water. Be sure to apply evenly, and take great care to ensure that the exterior is completely waterproof. The walls can then be painted with latex paint, using several coats.
The interior can be treated in the same manner. Environmentalists try to build these constructions using the least amount of wood possible. Interior papercrete walls are often painted just as the exterior walls are - with latex paint. A white lime wash, which is very nice looking, can be applied to the interior.
Flooring can be made from adobe, or a mixture of adobe and papercrete. Often, papercrete is used as a subflooring, thus making a good thermal barrier. Flagstones are also often used for flooring. Papercrete, unless mixed with greater proportions of cement, must be covered with another material because papercrete flooring by itself will be indented by heavy tables and chairs.
The Advantages of A Papercrete Home
So far, there has not been a lot of testing done on papercrete home. Because of its greater R factor and insulating qualities, papercrete homes use less energy. Smaller furnaces and air conditioning units can be used. You can use solar power systems in your home if you want to stay further off the grid.
Some Disadvantages
Papercrete has a tendency to absorb water, either through condensation or as an actual liquid. It is imperative that the papercrete home be well sealed, and that it is inspected frequently for any sign of leakage.
The cost of building a papercrete home as compared to a regular stick build is much less. Paper can be obtained easily. The only expense is for concrete and sand. Consider a papercrete house in you next attempt to live off the grid.
