Abstract
The importance of microstructure in materials science rests in its ability to establish links between processing and properties. Many properties of concrete are governed by structure at the nano-scale, notably by the variable and difficult to study calcium silicate hydrate. A basis for recent progress has come from viewing the nanostructure as a colloid or granular material (referred to here as C-G), with certain properties assigned to the grains and other properties assigned to reasonably well defined packing arrangements of the grains. This approach taps into both colloid science and granular mechanics. This approach is rich both conceptually and quantitatively. This paper describes recent progress using the C-G approach to understand drying shrinkage and creep, with a view towards further reconciling a vast literature, and improving quantitative relationships between structure and properties.
