Papercrete Test Panel

So here is our test for a papercrete wall panel.

This slideshow requires JavaScript.

We built a form 20″ x 20″ (dimensions were based on largest size of available materials for a form… i.e. being cheap and using stuff in the scrap pile)

Form material list:
(1) 20 ” x 20″ OSB board
(4) 2″ x 2″ for sides
cling wrap so papercrete doesn’t stick to OSB

Papercrete mix ratio 2:1 (Paper to Portland cement) The mix consistency was like wet oatmeal and we worked it into the mold by hand and troweled/hand-patted it to smooth it out.

Results are pretty encouraging. It’s been drying for three days and is about 1.5″ thick. The next test is a 4′ x 8′ panel. Stay tuned.

      1. I have wanted to build a geodesic outbuilding for my shop for quite a while now. Trying to learn from the Tucan bill, I put papercrete in my first triangle mold and after drying brushed on portland on one side and Grancrete on the other side, it breaks too easily, i will attempt to use portland soaked cloth for the outer shell on the next attempt with split bamboo to stiffen it up even more. Grancrete is too
        difficult to get and too expensive.
