Thanks for the replies. I am going to specify SIKA for the spall repair, and add a channel toed out with a cap plate under the beams, with epoxy anchors into the wall below the spalled area. The beams are not girders, but secondary members, so the reaction is not high.
I have been asked to give a possible reason and repair for the concrete spalling in the attached photos. I have asked for the concrete reports, but do not have them yet. I am looking for some general thoughts on what might be going on here. This job is located in the north, and was winter...
