Résumé en anglais

Marble is an attractive material used as aesthetically pleasing facade cladding on old and modern prestige buildings and as a preferred material for sculpture. However, outdoors, marble is more sensitive to weathering than many other stone materials and marble cladding on buildings often suffers damage in that the panels start to bow permanently in-situ on the building walls, and after few years a disastrous situation may develop. Recent research in the EU-project HERMES and elsewhere has shed new light on the deterioration process which appears tobe quite different from the deterioration of other stone materials.
Damage in marble is not caused mainly by air pollution but rather by temperature and humidity fluctuations which cause a fatigue-type failure in the grain boundaries of the marble. Rainfall directly onto the marble tends to accelerate the damage. Certain marbles are more prone to deterioration than other marbles ,probably as a consequence of their internal microstructure and their pore structure on a nanometer scale.
