The durability of such thin slabs (mostly 30-40 mm) is satisfactory at most constructions. However, on numerous buildings all over the world, the long-term deformation (expansion, bowing) of some claddings is associated with structural weakening and strength loss which led to an inevitable restoration of the affected facades and to an image problem of marble used as a structural building stone. Up to now, the existing knowledge about the causes for this special kind of marble weathering is mostly restricted to research on Carrara marble and to the effect of individual parameters. This thesis presents the first study of the combined influence of extrinsic (environmental) and intrinsic (material specific) parameters on marble bowing. The respective impact of these factors on the weathering process is elucidated by damage mapping of four different marble facades. The work focuses on the influence of the microfabric on the damage dynamics of veneer marble and particularly considers moisture as an essential climatic parameter. In order to characterize and understand the weathering process, an array of different marble samples had to be studied with regard to their petrographic, rock physical and microstructural properties. Besides both fresh and artificially weathered marble samples this survey also included demounted façade panels from the investigated buildings with varying degrees of pre-deterioration...}, note = { \url {http://hdl.handle.net/11858/00-1735-0000-0001-3083-B}}, }
