Many of the experimental advances in understanding interfacial transition zone (ITZ) microstructure and its role in the performance of cement-based composites have been either initiated or accompanied by advances in the computer modelliug of ITZ microstructure and properties. In the early stages of research in this area, conceptual models explaining ITZ formation and structure were proposed. With the advances in computational capability in recent years, these conceptual models have been substantiated and further developed via computer simulations. This chapter provides a review of the computational techniques that have been employed in these simulations and the results obtained, covering both ITZ formation and structure and the resulting effect on the properties of cement-based materials.
