Journal ArticleDOI
Ultrasonic pulse velocity for the evaluation of physical and mechanical properties of a highly porous building limestone.
TL;DR: Regression analysis showed a reliable linear correlation between UPV and compressive strength, which allows a reasonable estimation of the strength of Lecce stone by means of non-destructive testing methods such as the ultrasonic wave velocity.
Journal ArticleDOI
Novel multifunctional coatings with photocatalytic and hydrophobic properties for the preservation of the stone building heritage
TL;DR: In this paper, a mixture of nanostructured TiO2 and a fluoropolymer was applied on a limestone substrate, and the obtained coatings were proved able to provide the functionalization of the stone with simultaneous photocatalytic and hydrophobic properties.
Journal ArticleDOI
Durability assessment of nanostructured TiO2 coatings applied on limestones to enhance building surface with self-cleaning ability
TL;DR: In this article, the resistance of coatings applied on a compact and a soft limestone, which differ in roughness, porosity and cohesion features, has been investigated, and their effect on the coated surface was evaluated as film loss by qualitative/quantitative ESEM-EDS analyses.
Journal ArticleDOI

Antonio Licciulli,Angela Calia,Mariateresa Lettieri,D. Diso,Maurizio Masieri,S. Franza,R. Amadelli,G. Casarano +7 more
TL;DR: In this paper, the application of photocatalytic coatings on stone has been investigated for providing surface protection and self-cleaning properties without any thermal curing of the coated stone.
Journal ArticleDOI
Limestones coated with photocatalytic TiO2 to enhance building surface with self-cleaning and depolluting abilities
Angela Calia,Mariateresa Lettieri,Maurizio Masieri,Sudipto Pal,Antonio Licciulli,Valentina Arima +5 more
TL;DR: In this paper, the role of the substrates, the nature of the titania dispersions and the TiO 2 loads, in determining characteristics and properties of the photocatalytic stone surfaces, in order to obtain suited coatings for real applications on buildings was investigated by comparing coatings obtained from either water and alcohol based colloidal suspensions of TiO2 nanoparticles, which were synthetized by sol gel and hydrothermal process and sprayed with different loads on the stone surface.
