RE: Deformed Mesh Substitution in slab

[Subject Prev][Subject Next][Thread Prev][Thread Next]
The smaller bars are more likely to get bent down prior to and during
concrete placement.  Therefore bar support spacing should be reduced.

Subject:	Deformed Mesh Substitution in slab

Has anyone given serious thought to using deformed mesh in warehouse
slabs-on-grade instead of typical #4 at 18" o.c?


Warehouse building with forklift traffic

6 inch slab, 4000 psi, sawcuts at 15 ft centers, reinforced with #4 at
18" o.c. through the sawcuts (reinforcing required due to soils).

The subcontractor wants to substitute 80ksi deformed mesh of size #3 at
12" o.c. in lieu of the #4's.
