Some concretions may be hollow. The centre is empty or filled with loose powdery clay or sand, or a detached hard lump resembling a nut. The loose powder shows that iron oxide formerly cementing the grains has been drawn away from the middle and towards the outside, contributing to the hard iron oxide shell.

In more recent times, the wet process has been replaced by a dry process to save energy lost in the drying of the kiln slurry. A long-distance slurry pipeline was an ideal method to transport the limestone slurries for the wet process. The slurry pipeline allowed the cement manufacturing to be undertaken on a separate site to the limestone quarry.
