Abstract:
A discussion of the relative importance of the nano- and microstructure of concrete for civil engineers is presented. The significance of nanostructure on the engineering properties of hydrated cement paste with specific reference to the role of water is highlighted. Relationships between microstructure and volume stability, porosity, crystallinity, and strength of cement systems are described. The utility of micro- and nanostructural probes is outlined to facilitate understanding of engineering behavior such as creep.
