Can epoxy grouting to cement steel rod into existing concrete be substituted with polyester grout?
This has been suggested by the architect for a building of which I am the owner. The specification from the engineers suggests epoxy.

If this is for a structural element of the building, I'd personally stick with the recommendations of the structural engineer - he's the responsible design-professional-of-record.
The manufacturer of the polyester grout should have published literature indicating the performance of their product, specifically pull-out strength (based on hole diameter, bar diameter, embedment depth, etc.) If the architect is proposing polyester, then he/she should be able to obtain the manufacturer's published literature and forward it to the structural engineer for review and consideration. It may very well be an acceptable substitution.

Why is the architect proposing this substitution anyway? What does she or he see the as the benefit?
