In the mix of paper with cement what was is the rough percentage of cement for papercrete?
Basically the mix that I use mostly is: 50/50 paper and cement by dry weight, and the amount of water doesn’t really matter…just enough to make the slurry. This is for “pure” papercrete, without sand. For a more durable product that doesn’t shrink as much and is less likely to burn, add some sand to the mix, and reduce the amount of paper proportionally by wet volume. It is best to experiment and come up with a mix that works for what you are doing. Q: For stuccoing walls, it seems to me that paper and cement mix does not get wasted as much as a mix of fine earth and cement. Although not a major cost, we have to throw a couple of layers of mix in our Hawaiian dome after some of the mix just does not hold on the wall. Seems like a crafts and artist job, the better with your hands the less waste you get. A: Yes, it is a tricky business getting plaster to stick, especially to the inside of domes. I finally came up with a technique of throwing just a thin layer of papercrete on the bags
