Characterization and Modelling of Concrete-Concrete Interface
In recent decades, the use of hybrid construction in the concrete industry has been increasing due to the availability of new specially tailored types of concrete and the need to repair existing structures. In such hybrid constructions, the interface between the two concretes might govern the response of structural members under environmental or mechanical loads. However, limited understanding and knowledge are available to appropriately design these interfaces which can lead to unsafe or costly structures. Therefore, I am invested in characterizing the mechanical response of the interface between the two concretes and recommend methods for its appropriate modelling/design.
