Many stones marketed as marble are not authentic marbles but rather different sedimentary or metamorphic rocks with relatively softer compositions. It’s not uncommon for sedimentary rocks like limestone, dolomites, travertine, or metamorphic rocks like serpentinite to be sold under the label of marble.

Marble water absorption typically falls within the range of 0.1 to 1.0 weight%, while their compressive strength varies between 60 to 150 N/mm2, flexural strength from 6 to 20 N/mm2, and abrasion resistance from 15 to 40 cm3 / 50 cm2.

Marble’s versatility in terms of workability, polishability, and softness has ensured its enduring popularity in both architectural and art like sculptures.
However, a careful examination of marble’s weather resistance is crucial. Notably, polished marble should be shielded from outdoor exposure, particularly in urban settings, where the polish can degrade rapidly but the vast majority of marbles showcase resilience against weathering.
Installation of marble requires careful consideration of potential color variations caused by the interaction with mortars and grout compounds. Utilizing thin mortar layers is recommended to minimize the likelihood of significant color changes.
