The original formula was 70% paper, 20% sand and 10% portland. You are suggesting 66% portland to 33% paper. Why????? Testing on roof panels, for burn protection found that they go out and don't continue to burn at 50% paper, 50% portland.
I too found that lime made papercrete weak. Painting it with whitewash when done works well. I would like to hear more about the formula that was used, what kind of boots the building has as well as if there are any termite guards in place.

Lime in papercrete makes it hold too much water. You should have 2 lbs. of cement per pound of paper.
