Poly fibers make reasonable reinforcement in cement though not as good as steel or some of the expensive synthetics like Spectra or Kevlar. Glass fibers are mostly for crack control. Nylon is too stretchy as reinforcement, but Poly is better. Graphite is to brittle. PVA fibers are good.
These have been tested in mortar. Papercrete may be different. My gut says go for it.

Subject: [papercreters] Possible add to PC
| Working on pipeline, I have piles of junk Poly rope, I was wondering has anyone tried adding short poly fibers to PC. I know that fiberglass strands are sometimes added to concrete mixes when high strength is required. I was thinking of 1" long pieces and about 1/2 lb to tow mixer batch. I was thinking of using this mix in the roof. I know this will take away fire proofing but I was looking to add strenght. Any thoughts would be read over and over.Thanks. |
