In general , constraint embelded region is used to model bond between reinforcement and concrete. But I have to model surface to surface contact between reinforcement and concrete to model bond between them... Option is available in LS-DYNA but is it possible with ABAQUS .. how?
You can use linkage elements to model the interface between steel and concrete. The horizontal element will simulate the bond and the vertical will simulate the dowel action. Initially the nodes of the linkage, steel, and concrete will have the same coordinates, as the load applied the linkage elements will stretch representing the slip.
I hope this article may help:

All the best.

I think it is possible. You can use surface to surface interaction property to model the slip. Define the normal (maybe hard contact) and tangential (Friction) contact properties.
