Abstract:

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.
