[Ferro List] Basalt Fiber

[Lyle Gordon]

Chris,

I have used basalt fiber (6 and and 12mm length) which I got from a
company near Moscow called Kamenny Vek, http://www.basfiber.com/.

The outperformed fiber glass, stronger and stiffer however and they
performed well for for our project (a canoe) but we ended up switching
to Dyneema (ultra-high molecular weight polyethylene from Toyobo in
Japan) as we found it dispersed better in lightweight concrete and it
has a lower density (important when making a boat).

Not sure how easy the fibers are to come by in north america but they
seem to be gaining popularity over here, they probably would be good
for FC.

Check out www.Sudaglass.com , which mention applications and availability of both loose fiber and 25mm square mesh, and roving. According to the manufacturer this seems to be a very interesting replacement for both glass and steel reinforcement. Ferrocement made with this material should be expected to have a much larger temperature range. This temperature range is large enough to wonder if some new types of fc could be manipulated that could be used for kilns or ovens. Maybe PVA fibers added for a release of moisture from the portland cement. Interesting stuff - Thanks Steve! - chris
