I have been thinking of using Papercrete to build with. I learned about it on the internet. I have been very empressed with it for dry climates with a large temperature swing. Namely the Southwest. I decided to try a few blocks to get my feet wet, so to say. I took a bag of shreaded paper home from work to try. I mixed it in a bucket, and only used paper and portland cement. 1 5 galon bucket of schreaded paper and 2 lbs. of cement. added water and mixed. It will be a few days before its dry.
