“…Successively, the TiO 2 dispersions were applied on their surfaces by brush. These two lithotypes were selected because of their differences in morphology, especially in terms of open porosity which is around 30% for Noto stone [34] and 2% for Carrara marble [35]. For comparison, untreated stone samples were also studied (named REF).…”

“…It can be observed that Noto stone, due to its larger porosity, requires a higher amount of dispersed matter than Carrara marble to treat the same surface area. As a consequence, the absolute amount of TiO 2 deposited on Noto stone is higher than on Carrara marble, even if the effective residual remained at the surface is lower, due to the penetration of the nanoparticles into the pores (see Aesthetic compatibility section) [34,35].…”

“…The calcarenite weathering becomes even more important when we think of these rocks as building stones used in historical buildings and monuments that undergo degradation and damage due to the centuries of prolonged exposure to the atmosphere. The physico-mechanical characterisation of such lithotypes has been usually carried out to verify their use as construction and ornamental stones Walsh, 2003, 2007a;Anania et al, 2012) or to analyse their characteristics at a local scale.…”

“…These clays may be found, albeit in low concentrations, in many of the sedimentary rocks currently used in the construction industry or used in the past in our historical buildings. Some of the decay seen on buildings is therefore caused by the action of these minerals (Sebastian et al 2008, Colas et al 2011, Anania et al 2012.…”

The durability of a rock when exposed to decay agents is an important criterion when assessing its quality as a building material. Our study focuses on six varieties of natural stone (two limestones, one dolostone, one travertine and two sandstones) that are widely used in both new and historical buildings. In order to assess their quality, we measured and characterized their dynamic elastic properties using ultrasounds, we measured their compressive strength using the uniaxial compression test and we evaluated their durability by means of accelerated aging tests (freeze-thaw and salt crystallization). In order to get a full picture of the decay suffered by the different stones, we determined the composition and amount of the clay fraction of the six stones. We also observed small fragments subjected to the salt crystallization test under an environmental scanning electron microscope to study any textural change and measured the changes of colour on the surface with a spectrophotometer. Finally, we analysed the pore system of the stones before and after their deterioration using mercury injection porosimetry. We then compared the results for the different stones and found that dolostone obtained the best results, while the two limestones proved to be the least durable and had the lowest compressive strength.
