epoxy dowel embedments?
(OP)
I am working on a project where the plans specify epoxy dowel installation according to ICBO ER-5193 (also allows for Simpson SET). My question is, is there a standard minimum embedment depth specified for a certain size bar that one can use on a jobsite (that's what the plans imply)? I think this contractor is looking for a catch-all for his beam-to-slab, curb-to-slab, slab-to-wall, ect. connections.
PS. None of these embedments, or dowels for that matter, are on the plans themselves.

Is there a reason you're not using the RE500 epoxy (ICBO Report ER-1682)? It looks like you get a lot more bang for your buck.

Yes, I was wondering about the long-term effect, especially after hearing about ceiling tiles in a tunnel falling on NPR, I believe in Chicago. Looks like, however, given the wide use of 'quick set' epoxy, that there'll be a lot of building concerns with long-term strength. This stuff's used all the time.
The problem with asking the engineer is that it takes a few days to get an RFI actually to the jobsite. With all the small (and large) epoxy jobs we have, it would just be rediculous to get RFIs for each of these. Maybe I'll just ask for a blanket statement for the life of the project.
Thanks for the good posts.

In the area of the midwest where I work, dowels are generally smooth bars designed for shear transfer. The only time that epoxy is used with them is to ensure complete contact between the bar and the concrete, i.e. to fill the oversize portion of the drilled hole.
We use the term reinformcment if there is a tensile load component.
Now for the quesiton, how does this compare to other areas of the country?

what diameter are your 15m rebar? I think 6" (152mm) is too short an embedment. What load do you use for the tension test?
I would have thought it would be better to use the manufacturer's literature to select the hole depth and diameter. Then use a hollow jack to carry out a couple of off-site tension tests on bars installed into a block of the same grade concrete. Once the tets have been carried out then the operation should proceed under supervision.

You could easily develop standard tables for full cones for various f'c values for various types of bars with no problem. The edge conditions would be the special designs.
