Here is Bill Birdsall INFO -- he talks about the mountains of
plastic fishing twine that is usable, so yes if it can be chopped to
1-3" in why not?

AKK-- his site below is NO longer up!! I have the 13 page- 1.4MB
file in PDF I can send to anyone who requests it directly-- and below
is a post he made in o4 on the ferrocement.net site--
From: "Bill Birdsall" <billbirdsall@hotmail.com> Date:2002-04-09
I would like to share my experience with a new material combination I
have been working with for many years. Nylon-cement is a combination
of recycled nylon fishnet and cement. It has lots of good uses, such
as making 1/4 inch thick cement floors, lining carved earth shapes
such as outdoor furniture, and above-ground structures.
Visit my web pages for more details. BOTH DON'T EXIST >

An essay on nylon-cement and the projects I have done with it are at:
www.angelfire.com/in2/manythings/page5.html
The nylon fishnet can stretch, so it doesn't prevent cement cracking,
but it does hold pieces together if they do crack, preserving
function. It doesn't rust, like iron, which is an advantage. About
the only thing that hurts nylon is ultraviolet light, and the cement
protects it from sunlight, so it should be a material combination with
pretty good longevity.
My house, which is dome-like, was built over a steel rod structure,
like ferro-cement, but all of the carved-earth work, including a
tunnel, uses no iron. There are above-ground techniques, such as
stretching the fishnet like a tent and then plastering it, that also
use no iron.
Iron rods rusting have caused me some problems already in the house.
The old rod manufacturing technique was to let the red-hot rods cool
slowly in the air, which let carbon fibers form in the rods, and
allowed oxygen to enter the rod and rust it faster. Water-cooled rods
have fewer carbon fibers in them, and are more rust resistant. None
of the supply stores here in Puerto Rico seem to be conscious of that.
I hope the industry has shifted over to water-cooled rods now. Not
to do so would be a disservice to all builders.
I also use silicone rubber to make architectural models. It is great
for making irregular shapes representing ferro-cement, or nylon-cement
structures. I will write up something on those model making
techniques soon. -- Bill

SO it has been done and may add interconnecting tensile strength.. If
I had access I would use it, as I use sawdust and it is tiny-- and
having nylon fivers to add wouls help. I did buy a sack of a Japanese
fiber- super strength Kuraray inc. they are online qand their PVA
FIBERS ARE DESIGNED SPECIFIC FOR CEMENT USE.
THEY WERE SHOWN AT THE ITSA ( thin shell assoc.) conference, IN
OREGON 3 YEARS AGO..
A 40 PD BAG LASTS FOREVER, AND THE TINY FINE FIBERS DO THEIR JOB.
opps capps!! see the site on cement reinforcement
