The steel–concrete interface SpringerLink

2017-2-27  The steel–concrete interface (SCI) influences the structural behavior and durability performance of reinforced concrete, and thus, plays an important role in engineering of reinforced concrete structures. The SCI has a particular influence on the corrosion behavior in chloride exposure environments and in the case of carbonation.

2012-10-12  The role of this interface element (between steel and concrete) is: To ensure the displacement continuity between the concrete and the steel before the interface slipping (i.e. tangential relative displacement) and before the concrete cracking. So, it ensures the transfer of the load (and therefore of stresses) between steel and concrete.

The interfacial zone consisted of (a) a thin (1 or 2Μm thick) duplex film in actual contact with the reinforcement, (b) outside of this, a zone of perhaps 10 to 30Μm thickness, which, in reasonably well hydrated systems, is largely occupied by relatively massive calcium hydroxide crystals, with occasional interruptions of more porous regions, and (c) outside of this, a highly porous layer parallel to the interface.
