Building With Papercrete Pdf Free: A Practical Guide to Making and Using This Recycled Material

# Building With Papercrete: A Guide to Making and Using This Eco-Friendly Material ## Introduction - What is papercrete and why is it useful for building? - How is papercrete made and what are the basic ingredients? - What are the benefits and limitations of papercrete? - What are some examples of papercrete projects and applications? ## What is Papercrete and Why is it Useful for Building? - Papercrete is a type of industrial strength paper maché made with paper and cardboard, sand and Portland cement - Papercrete can be mixed in different proportions to achieve different properties and strengths - Papercrete is useful for building because it is lightweight, insulating, mold-resistant, sound-proofing, and strong - Papercrete can be used for making low-cost homes, community rooms, storage rooms, livestock dwellings, and plasters ## How is Papercrete Made and What are the Basic Ingredients? - Papercrete is made by pulping paper and cardboard with water in a mixer, then adding sand and cement to form a slurry - The slurry is poured into molds or forms and dried in the sun - The basic ingredients of papercrete are: - Paper: usually waste paper such as used newsprint or cardboard - Sand: coarse or fine aggregate depending on the desired strength of the papercrete - Cement: used as a binder and to provide rigidity to the papercrete - Water: used to pulp the paper and to hydrate the cement ## What are the Benefits and Limitations of Papercrete? - The benefits of papercrete are: - Raw materials are very inexpensive and freely available - Equipment used is relatively low-tech and inexpensive - Has high compressive strength and considerable tensile strength - Has excellent heat and sound insulating properties (R 2.8 per inch) - Papercrete is light weight and can be used to make inexpensive roofing alternatives - Papercrete is very workable and can be formed into different shapes such as blocks, panels, and sheets with ease - Papercrete does not catch fire easily but smolders for hours - The limitations of papercrete are: - Poor moisture resistance and disintegrates when exposed to water for prolonged periods of time - Susceptible to termite and mold attack - Low longevity and expands and contracts frequently leading to cracks and buckling - Poor tensile strength compared to other building materials - Lacks standardization and code compliance in most places ## What are Some Examples of Papercrete Projects and Applications? - Some examples of papercrete projects and applications are: - Homes and small commercial buildings constructed with papercrete as an in-fill wall in conjunction with structural steel beams or other load-bearing elements - Community rooms, sale booths, storage rooms, and dwellings for livestock made with papercrete blocks or panels - Plasters sprayed on walls to give them good sound and heat insulating properties - Model structures that demonstrate the strength and durability of papercrete - Artistic sculptures and decorations made with papercrete ## Conclusion - Papercrete is a versatile and eco-friendly building material that can be made with recycled paper, sand, and cement - Papercrete has many advantages such as being lightweight, insulating, mold-resistant, sound-proofing, strong, inexpensive, and workable - Papercrete also has some drawbacks such as being moisture-sensitive, termite-prone, low-longevity, unstable, weak in tension, and lacking standardization - Papercrete can be used for various projects such as homes, community rooms, storage rooms, livestock dwellings, plasters, models, sculptures, etc. ## FAQs - Q: How do I make papercrete at home? - A: You will need a mixer (such as a tow mixer or a barrel mixer), a mold or form (such as a wooden box or a metal sheet), waste paper (such as newspaper or cardboard), sand (coarse or fine), cement (Portland or masonry), and water. You will also need a scale to measure the ingredients and a tarp to cover the mold. The steps are: - Soak the paper in water for a few hours or overnight - Shred the paper with the mixer until it becomes a pulp - Add sand and cement to the pulp and mix well until it forms a slurry - Pour the slurry into the mold and level it with a trowel or a spatula - Cover the mold with a tarp and let it dry in the sun for a few days or weeks depending on the weather and the thickness of the papercrete - Remove the papercrete from the mold and use it as desired - Q: How do I plaster a wall with papercrete? - A: You will need a sprayer (such as a mortar sprayer or a texture sprayer), papercrete (made with more water and less sand and cement than for blocks or panels), and water. The steps are: - Wet the wall with water to help the papercrete adhere better - Load the sprayer with papercrete and spray it on the wall in thin layers - Smooth out the papercrete with a trowel or a spatula as you go - Let the papercrete dry completely before applying another layer if needed - Finish the papercrete with a coat of paint or sealer if desired - Q: How do I make papercrete stronger and more durable? - A: You can make papercrete stronger and more durable by: - Adding more sand and cement to the mix to increase the density and rigidity of the papercrete - Adding fibers (such as hemp, sisal, or nylon) to the mix to increase the tensile strength and crack resistance of the papercrete - Adding additives (such as lime, fly ash, or silica fume) to the mix to improve the hydration and bonding of the cement - Curing the papercrete properly by keeping it moist and covered for at least a week after drying - Sealing the papercrete with a waterproof coating or membrane to protect it from moisture and weathering - Q: How do I make papercrete more eco-friendly? - A: You can make papercrete more eco-friendly by: - Using recycled paper as much as possible to reduce waste and save trees - Using natural or organic materials (such as clay, lime, or straw) instead of cement to reduce carbon emissions and environmental impact - Using local or renewable materials (such as sand, gravel, or wood chips) instead of imported or non-renewable materials to reduce transportation costs and energy consumption - Using less material and making thinner walls to reduce weight and resource use - Designing your project to maximize natural light, ventilation, and insulation to reduce energy use and improve comfort - Q: Where can I learn more about papercrete? - A: You can learn more about papercrete by: - Reading books, articles, blogs, and websites about papercrete (such as,,, etc.) - Watching videos, documentaries, tutorials, and demonstrations about papercrete (such as Papercreteman's YouTube channel, Papercrete: The Movie, How to Make Papercrete Blocks, etc.) - Joining online forums, groups, communities, and networks about papercrete (such as Papercreters on Facebook, Papercretenetwork on Yahoo Groups, Papercretenet on Twitter, etc.) - Attending workshops, courses, seminars, and events about papercrete (such as Papercrete Workshops by Barry Fuller, Papercrete Building Course by Zach Rabon, Papercrete Conference by Mike McCain, etc.) - Visiting projects, sites, buildings, and structures made with papercrete (such as Earthship Biotecture in New Mexico, Paper House in Rockport Massachusetts, Paper Dome in Taiwan, etc.)
