I'm about to order concrete for a tower base. The concrete company offers
fiber reinforcement mixed into the concrete for about $10 per cubic yard.
I've researched concrete fiber and found nothing on Tower Pro and only one
comment here by K7LXC saying it wasn't needed.
It appears that the fiber adds 5-10% additional compressive strength and
about results in a 50% reduction in cracking. (it is touted as a replacement
for embedded steel mesh in slabs.)
I have been unable to find any literature indicating that it is
inappropriate for tower bases or even any negative consequences of its use
for such. For less than a 10% increase in the cost of the concrete, it seems
like it may be worth it- even if only for a belt and suspenders approach.
Does anyone have any experience with concrete fiber use in tower
foundations?
Tnx,
Doug
