Much recent research on the materials science of
concrete has focused on the characteristics of the
interfacial zone between cement paste and aggregate and
its effects on mechanical and other properties. This
chapter reviews recent computer modelling work on these
topics, including the formation mechanisms of
interfacial zone microstructure, the effects of cement
paste and aggregate physical properties on this
microstructure, the percolation of individual
interfacial zones as a function of aggregate size
distribution and content, and the mechanical and
transport properties of cement paste-aggregate
composites. Model results are compared with
experimental results from the available literature.
