“…Angeli et al (2007) tested sandstones and limestones and, their results show a continuous decaying of the weight measured each cycle, and they do not report an increasing stage as the one observed in the tested samples in this work. However the total of salt bursting cycles realized with the studied samples before their total decay corresponds perfectly with the behavior of other analyzed volcanic tuff rocks (López-Doncel et al, 2016).…”

ABSTRACTHigh porosity volcanic tuffs were used to elaborate the masonry of the walls of the Cathedral of Aguascalientes City, at central México. At present, masonry stones show evidences of deterioration, mainly in the lower part of the walls outside the building due to a raising moisture effect and environmental pollution which are causing damages such as flaking, scaling and black crusts. Petrological studies including X-Ray diffractometry and petrophysical analysis as porosity, density and bulk-density determinations as well stone damages survey were carried out to get information on the used rock types to elaborate the masonry walls, their petrological characteristics and physical harms. No compresional testings were developed due to scarse of stone samples, but there are reported data for these stones by others authors. The results allow to identify the stone type most prone to deteriorate, the mechanism of stone deterioration, and the factors accelerating deterioration. Although results have a pragmatic use for restoration works of the Cathedral of Aguascalientes City, the methodology applied could be used for determining the stone vulnerability to deteriorate in heritage buildings anywhere abroad.Key words: tuff rock; moisture properties; cultural heritage; Aguascalientes; Mexico.

Abstract. Cantera is a quarry tuff widely used in the building industry; in this work the shielding features of cantera were determined. The shielding characteristics were calculated using XCOM and MCNP5 codes for 0.03, 0.07, 0.1, 0.3, 0.662, 1, 2, and 3 MeV photons. With XCOM the mass interaction coefficients, and the total mass attenuation coefficients, were calculated. With the MCNP5 code a transmission experiment was modelled using a point-like source located 42 cm apart from a point-like detector. Between the source and the detector, cantera pieces with different thickness, ranging from 0 to 40 cm were included. The collided and uncollided photon fluence, the Kerma in air and the Ambient dose equivalent were estimated. With the uncollided fluence the linear attenuation coefficients were determined and compared with those calculated with XCOM. The linear attenuation coefficient for 0.662 MeV photons was compared with the coefficient measured with a NaI(Tl)-based J-ray spectrometer and a 137 Cs source.

“…As such, they differently respond to environmental changes and stresses, producing strongly localized mechanical fatigue at the interface with the underlying host rock. The stresses generated by cyclic salt crystallization alone are acknowledged as a major decay cause [50][51][52][53].…”

Volcanic tuffs have a historical tradition of usage in Northern Hungary as dimension stones for monumental construction, Ottoman architecture, common dwellings, etc., admirable at its best in the medieval castles of Eger and Sirok. This research explores tuff deterioration in the castle walls, dealing with the mineralogical composition, microstructure, trace-element geochemistry, and microporosity of the surface weathering products and the near-surface stone substrate. The classic microscopic and mineralogical techniques–optical microscopy, SEM-EDS, and XRD–were supported by ICP-MS and nitrogen adsorption analyses. The textures and mineral assemblages of the tuffs are partly diverse, and so are the weathering characteristics, although including common features such as secondary crystallization of gypsum, swelling clay minerals, and iron oxides-hydroxides; deposition of airborne pollutants, i.e., carbon particles and heavy metals; formation of crusts and patinas; decreased surface microporosity. Nonetheless, the entity of deterioration varies, in relation to air pollution–involving changing emissions from road and rail transport–and the specific tuff texture, porosity, and durability–affecting pollutant absorption. The studied stone monuments offer the possibility to examine materials with analogue composition and petrogenesis but utilized in different environmental contexts, which allow pointing out the environmental and lithological constraints and cause-effect relationships related to surface weathering.
