The County required the fiber for the house slab, they also
required 3500PSI.
While they were here we had them pour the tower base, driveway
slab, and 18" sills around the house (so water off the roof
hit the sloped sills and bounce away vs drilling a hole and
splattering mud).
We had the house slab and all of the concrete, including
the tower base, sealed.
At the end of the day the most important factor in the
strength and longevity of concrete appears to be how
consistently and thoroughly it is kept sufficiently moist
during the curing period.
IMHO, YMMV ...
