RE: Slab on grade

[Subject Prev][Subject Next][Thread Prev][Thread Next]
It depends on the gauge of the WWR and the spacing of the dobies.  The #3's with dobies at 4' o.c. will (in general) rebound easier than lighter gauge WWR.

Is a #3 much better than WWF after a few hefty guys walk all over it?

This means that in your 4" slab, rebars at 12" spacing do not necessarily have to be #4, they can be #3 placed about 1.25" below TOC.
