The Visible Cement Data Set website has been created and is currently being populated with the various data sets collected during the experiments conducted at the ESRF facilities. The three-dimensional data sets available from the site are presently unique in the world due to their high spatial resolution (voxel size less than one micrometer). The data sets should find usage in a variety of research and educational environments as the web site has been created with the primary objective of increasing the accessibility of these unique data sets. While a few example applications (determination of w/c and degree of hydration, assessment of percolation, computation of physical properties) have been discussed and presented in this paper, it is likely that other uses for this three-dimensional data will be discovered and implemented over time.
