Hello Kim
Hope things are going well on your project. I finally finished my Papercrete just before Thanksgiving. All and all it was about 2,000 cubic feet to pour. I used a slip form. We poured new Papercrete walls against our existing Mobil home. W' e have free standing Papercrete at the addition. I have enclosed a picture of the form system and the finished pour. I still have to do the skim coat and waterproofing coat.
To the Flyash issue, I have not heard of flyash as a stand alone binder. Typically in concrete it is used as a supplement to cement to reduce the amount of cement required.
Before i began construction on our house i built a barn as my testing lab. for my initial work I tried to maximize paper and minimize binder. I did a mix with lime and wood ash that was very promising. The logistics of trying to get that much ash mad it seem like more than I could manage.
The mix i test was ( by weight)
paper 28%
clay 40%
Wood ash 19%
lime 13%
This was a stronger product than what i was getting with what I thought was comparable with cement. When I finally got a mix that I thought was what i need i got some compression tests. Compression strength was way too low.
Based on my final cement mix I think you can test a mix with these proportions ( by weight)
Paper newsprint) 14%
Clay 15%
Sand 27%
Ash 27%
Lime 17%
Please let me know what you come up with.
Best
Murry Holley
