Re: Concrete Cover Over WF Beam

[Subject Prev][Subject Next][Thread Prev][Thread Next]
Will,

What is going to stop the 3/8" of topping concrete from breaking up into little pieces over time with a little bit of movement, deflection etc? I seems awfully weak to me!

I have a case that is very similar to the following detail. I am only going to have 3/8" of concrete cover over the top of the WF beam.

Does any preparation to the beam typically done (sandblasting, applying epoxy) in order to insure the bond of the concrete to the top flange of the beam? This cover is not structural, is there a minimum cover recommended?
