Petrophysical-mechanical behavior of Grisolia stone found in the architectural heritage of southern Italy

Abstract

Grisolia is one of the building stones most commonly found in the architectural heritage of southern Italy. Also known commercially as “gold stone” for its yellow intrusions, Grisolia was employed by the leading Calabrian schools of stonemasons, principally in the southern Italian regions of Calabria and Basilicata. It is an Upper Triassic crystalline carbonate quarried in the Verbicaro Unit on Calabria’s northern Tyrrhenian coast.
 
 Possessing petrographic, physical and mechanical properties that ensure stone strength and durability, it is a high-quality building material suitable for structural and ornamental uses. These properties can be attributed to its low open porosity and excellent hydric behavior (low capillary water absorption), as well as to its high mechanical strength and low anisotropy. These characteristics make it recommendable as a building material for both restoration and new construction.

Urban Sprawl and Mobility

“…The preservation of the natural environment and the architectural heritage [38], [39] is included in the TOD model as large green bands among the areas of urban growth are respected. Moreover, the modular radial urban structure does not prejudice the possibility of further expansion since free areas are devoid of widespread low-density settlements.…”

Demanda Gold sandstone (Burgos): effect of consolidation and ageing tests on its petrographic and petrophysical properties

“…Sandstones' great compositional and textural variety means their physical and mechanical behaviour differs widely. It is therefore necessary to characterise their petrographic and petrophysical parameters in order to assess their quality as a building material and predict their medium-and longterm behaviour and durability (2,3,(7)(8)(9)(10)(11)(12).…”

Upper Cretaceous Limestones as Stone Resources for the Monuments of Oviedo (Asturias, NW of Spain): Petrographic Variability and Stratigraphic Origin

“…In these cases, it is convenient to know the origin of the material: the geographical and geological location of the lithotypes, the exact formations, or even outcrops of origin (Fronteau et al 2010;Bone 2016;Carter et al 2017;Ajanaf et al 2020). This information will make it possible to locate a stone that is similar to the original in characteristics and properties and, so, in behavior (Bugini and Folli 2008;De Kock et al 2015;Zoghlami et al 2017;Anania et al 2012;Forestieria and Álvarez de Buergo 2019), and to find the most suitable material to replace ashlars or other construction elements in heritage restoration works. Some authors deal with sustainability in the use of geological resources and highlight the interest of local stones, together with reusing/recycling waste materials, as a source of supply of raw materials for construction, in line with the EU policy in its Europe 2020 strategy (Dino et al 2018).…”
