Limestone is a brittle rock that can break down and dissolve over time. External factors can cause the stone to crumble, like if it isn't properly sealed and is then overused. You will want to prevent sealants from wearing away completely by paying attention to maintenance so you can address resealing before it becomes a problem for the flooring.

Limestone mainly consists of hard brittle minerals, such as quartz, ankerite, calcite, pyrite, with area percentages of 65.91–59.56%, 21.50–9.22% and 2.34–1.36% respectively. Water-sensitive minerals could be identified in the specimens, such as illite and chlorite, with an average area percentage of 2.32% and 1.57%, respectively.

Brittle creep of the limestone is associated with dilatancy and the development of a shear fault at final strains lower than 2%, as previously observed for other brittle materials. Semibrittle creep leads to inelastic compaction accommodated by crystal plasticity and then to dilatancy likely due to the nucleation and propagation of cracks at ...
