WWF in slabs to reduce cracking due to thermal expansion and contraction.
Small, fine surface cracking is usually due to too rapid evaporation of
water (drying) from the surface before it cures.

As far as I know its to prevent surface cracking which while it doesn't
affect the structure of the slab, looks nasty... Very common in garages I'm
given to understand.

OK -- Why do concrete slabs have heavy, welded wire fabric (WWF) in them; or
even fiberglass strands mixed into some?
