NDT&E techniques and SEM‐EDS for the assessment of cleaning interventions on Pentelic marble surfaces

Abstract: In this work, several non‐destructive testing and evaluation (NDT&E) techniques along with scanning electron microscopy with energy dispersive x‐ray spectroscopy (SEM‐EDS) were applied on Pentelic marble surfaces. The investigated Pentelic marble surface disclosed a representative decay pattern that usually develops in polluted urban atmosphere such as the Athens centre. The applied techniques aimed to collate as much as possible evidence about the physico‐chemical and aesthetical characteristics of the examin… Show more

“…Soil-repelling properties are desired, they depend on the composition of the material exposed to the environmental agents but also on its roughness which includes the finest irregularities of a surface and depends on the chemical and mineralogical composition of the material, on the type and conditions of the production process 5 . Besides being related to the susceptibility of the surface to decay [6][7][8] roughness also affects the optical properties of a material: gloss and colour saturation varies when roughness increases, because of the enhancement of reflected light and the reduction of subsurface light scattering 9 . Furthermore, roughness can cause water detection and the change of the water absorption speed, changing in turn the surface colour 10 .…”

“…SEM-EDX is a powerful tool for the aforementioned aim, since diverse data regarding texture, morphology, and composition can be collected about the “composite” system of conservation material-historical substrate, for many aspects of conservation science such as (a) optimisation and performance assessment of consolidation treatments using nanolime materials [ 19 ], novel inorganic methods [ 55 , 56 ], and hybrid nanomodified materials [ 57 ]; (b) assessment of water repellent performance regarding their penetration into porous stones [ 58 ]; and (c) assessment of cleaning treatments on stone crusts [ 59 , 60 ], and on different types of graffiti [ 61 64 ].…”
