Will this stuff make decent concrete reinforcement additive if shredded? It's orders of magnitude cheaper than the white uniform length fibers you usually see in GFRC...

It's quite puffy and thin like wool, so it probably will only introduce air poquets.
If you reduce it to the fibers, they are so thin it probably won't add much reinforcement.
The ideal thing is having sommewhat thick strands in random directions without puffing up.
