Epoxy coated bars, adhesive anchorage, and high temp
Epoxy coated bars, adhesive anchorage, and high temp
(OP)
During a job we had to demolish out a 12 inch area of a curb around an opening in an industrial plant. We're now putting the curb back using epoxy anchored dowels 5.75" O.C., 7" into the existing slab. The area frequently gets to 110 degrees so I specified a limited creep epoxy. I was right on the edge of my required strength per appendix D and the manufacturer of the epoxy anchorage system.
They're starting today and I go out to the site and they've brought epoxy coated rebar...
I can't find anything from the manufacturer or elsewhere of what this will do for the bond strength of the epoxy anchorage system but I don't like it. Anyone have a reference I can cite that I can quote to contractor to get them to just give me some plain bars? They're going to hate me bending another couple hundred dowels but I don't see any way around it. If someone leans on the railing attached to this curb they're looking at a 370 foot fall.

The greatest trick that bond stress ever pulled was convincing the world it didn't exist.
