CMU Wall Sitting on a Concrete Slab

[StructuralEngGuy]

Hi all,

Does anyone know if there's any code requirements for the surface where the CMU will sit on a concrete slab? I.E. does the concrete surface need to be roughened to a minimum amplitude?

Thanks!

Why? I have never seen that done.

No. That's what the rebar stubs are for.

You will get some additional shear from the bond between the concrete slab and wall mortar too.
