Very good step-by-step to make #Papercrete. A mix of about 3 parts paper pulp, 2 parts Portland cement and 1 part perlite. Lighter than hyperturfa and perfect newspaper recycling. Should also be good to make #raised beds and #retaining walls.
How To Make Papercrete: Papercrete is a cement with fibers of some kind in it. These fibers can be just about anything, from paper and cotton to hemp, jute, flax, wool ect. These fibers add strength to the cement, just as glass fibers add strength to fibreglass. In the case of papercrete, these fibers can actually make up the bulk of the mix, resulting in a product that is both lightweight and strong.
Papercrete (like hypertufa) basic recipe: approximately 3 parts paper pulp, 2 parts portland cement and 1 part perlite and other optional fillers. Getting the paperpulp made to the right consistency is key. Too wet and the mixture is slumpy and if too dry – crumbly. Make small batches to experiment and get your mixture to your liking.
