Welcome to the group, Theo. With your inclination toward math and 3D solids packing, you should check out the Geodesic Math & Alternative Structures group. Also, you might consider the testing coordinator's job that the code team is trying to fill. It looks like you might have the skills to do it well. We need someone with good organizational skills, and the ability to analyze test data.
As far as styrofoam in papercrete, I have tried it and didn't like the results. The pc shrunk away from the foam, leaving voids, and did not bond well with the plastic at all. I did not see any advantage to using it, and saw several disadvantages, difficulty of mixing being one. Your phrase "compared to normal concrete" indicates to me that you should mix some papercrete and play with it, then you'll see that pc is nothing like "normal concrete". It's an entirely different material.
Rastra blocks are great stuff, just a different thing from pc. Why replace free green recycled paper with a nasty non-green plastic?
