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.
GREAT for GARDENING - Hypertufa is a product that looks like cement but weighs less. A woman can actually manage to lift containers made out of hypertufa. It's a mix of Portland Cement, Peat Moss, Perlite and fiberglass fibers.
made these rocks out of boxes covered with garbage bags, then covered the boxes with chicken wire, then covered rock with about 3 inches of pigmented hypertufa (portland cement, sand, peat moss mix). Gardenweb has a hupertufa forum that is interesting.
Hypertufa. Hypertufa is a mixture of Portland cement and other ingredients such as peat moss, sand, perlite, or vermiculite and water. It is used to make fake rock containers and other items. Once fully cured, it is weatherproof and should not crack during freezing temperatures. People like it because it can be lighter in weight as compared to concrete or stone, but it has a similar look.
