The process consists of adding a certain ratio of paper and / or cardboard to water and then adding portland cement. The mixture is then stirred with a blade to re-pulp the paper and mix everything together. When it is properly mixed it becomes a slurry that has the consistency of lumpy oatmeal.
Is papercrete as strong as concrete?
I found that the concrete was the strongest, holding 84.45 times its own weight, while glossy papercrete held 40.45 times its weight, and newspaper papercrete held only 7.11 times its own weight on average.
How do you make a papercrete house?
You make papercrete by taking old newspaper, phone books, and/or cardboard, and mixing it up with a lot of water until the paper is pulped. Then you add the cement and voila… yuckie sticky globs of goo that make perfect block walls or sculpted structures.
How do you make papercrete waterproof?
Silicone-based water-proofing formulas that are absorbed into the papercrete seem to work well. Another option I recently found out about is Geobond, which could provide a fast, durable solution to sealing, fireproofing, and scuff-proofing papercrete (www.geobond.net).
Is papercrete waterproof?
Papercrete is fire resistant. Fire resistance can be increased by adding more Portland cement or mineral material. They also found that coating papercrete with a concrete sealer made the blocks waterproof.
Is papercrete heavy?
Unlike concrete or adobe, papercrete blocks are lightweight, less than a third of the weight of a comparably-sized adobe brick.
Is papercrete a good insulator?
Papercrete is among the best metarials to use to insulate your zero energy house. it’s insulation values are excellent.
Can you paint papercrete?
Painting – You can easily paint your finished papercrete projects. Adding junk – Some people even add more recycled junk materials like shredded plastic waste, to reuse these materials in a greener way.
How long does it take for papercrete to dry?
Take your time patting and smoothing the papercrete. You have about two hours from the time the Portland cement is added before the medium begins to harden. Once you are satisfied with your creation, place the finished product where it will be able to cure for at least 24 hours.
Is papercrete fireproof?
My suggestion for would-be papercrete builders is to not make a roof out of it and keep it out of the ground. This also tends to make the product much more fire resistant, since the straight papercrete can smolder if it gets hot enough.
What is hypertufa mix?
Hypertufa is a lightweight, porous material used in craft projects. It is made from a mixture of peat moss, Portland cement, and either sand, vermiculite, or perlite. After mixing the ingredients together, they are molded into shape and allowed to dry. Hypertufa projects are limited only by your imagination.
What is papercrete brick?
Papercrete bricks were prepared out of waste paper, and quarry dust with partial replacement of cement by another industrial by-product Fly Ash in varying proportions of 25%, 40% and 55%. Based on the study it was found that for non-load bearing walls papercrete bricks are best suited.
Who invented papercrete?
Papercrete was first patented in 1928 by Eric Patterson and Mike McCain, who ‘invented’ it independently as ‘padobe’ and ‘fibrous cement’ respectively.
What is Timbercrete made of?
Timbercrete is made of a unique blend of cellulose (timber waste), cement, sand, binders, and other materials. As the name suggests “Timber-crete” is made primarily from timber waste such as sawdust or recycled timber from discarded pallets and the like. No trees have been cut down specifically to produce Timbercrete.
What can I add to cement to make it lighter?
Using less sand can make the product lighter, but it can also make the concrete weaker structurally. A simple recipe for basic lightweight concrete is to combine 8 parts sand, 8 parts cement and 8 parts perlite to 5 parts water.
What is the difference between Portland cement and cement?
Although the terms cement and concrete often are used interchangeably, cement is actually an ingredient of concrete. Portland cement is not a brand name, but the generic term for the type of cement used in virtually all concrete, just as stainless is a type of steel and sterling a type of silver.
How do you make Woodcrete?
We create the woodcrete by chipping specially graded recycled waste wood into wood fibre and then mineralising the chips to neutralise the natural sugars. After mineralisation, the wood chips are bonded together with Cem 1 cement.
Where is papercrete used?
Papercrete is suitable for making low cost homes with limited longevity and durability. It is also suitable for making community rooms, sale booths, storage rooms and dwellings for livestock. Papercrete can also be used as a plaster. It can be sprayed on walls to give them good sound and heat insulating properties.
Is papercrete green?
Papercrete offers a fairly inexpensive way to build well-insulated walls for houses and potentially reduces waste paper that would otherwise be sent to the dump. Q: Do you use papercrete just because it is ‘green’ and good to recycle newspaper or is it better as insulation than traditional mortar? A: All of the above.
How strong is rammed earth?
The compressive strength of rammed earth is dictated by factors such as soil type, particle size distribution, amount of compaction, moisture content of the mix and type/amount of stabiliser used. Well-produced cement-stabilised rammed earth walls can be anywhere between 5 to 20 MPa.
How is translucent concrete made?
Translucent concrete is made by combining two major materials; fine concrete (with cement and aggregates like sand) and optical fibers. These optical fibers replace other concrete aggregates, and conduct light from artificial and natural sources even at an angle of incidence of more than 60 degrees.
