Thanks to all for the responses.
Please note that the wood ash is only .5 pounds in the overall 12.5 pounds. We put it in after reading about pozzolanic ash. This ash may have only a small proportion which is pozzolanic but we have observed that the fully dried block is harder and I think somewhat more impervious with the small amount of ash.
As far as water goes, we watched the videos and read stuff by Mike McCord and got the idea that the water is not a measured ingredient. When the papercrete mix is put in place, clear water runs out rapidly and the material settles. So the water in it was excessive to start. Is that how others do it?
We put the material into a form and stood two 2-liter bottles in it to make that block. I am not sure this is an efficient enough process to make enough blocks for a building. But we were trying to get a good result even if it was a small batch. The block looks quite good.
