Abstract Arucas Stone ( Piedra de ) is a welded tuff quarried in the town of Arucas, on island Gran Canaria Canary Archipelago. This rock has been for centuries, not only building but also many other purposes, such as manufacturing water cisterns or conduits, and especially carving. The quarrying economic activity related to this stone have profoundly shaped history economy city terms extraction, highly valued local artisan tradition Immigrants from Islands even brought several countries...
Abstract Water plays a fundamental role in rock weathering processes. Its penetration and movement inside rocks greatly influences the nature intensity of damage affecting building stones. X-ray computed tomography (CT) is useful technique for non-destructive mapping water penetration. For reported study, CT was used to investigate internal structure patterns Piedramuelle Stone, Cretaceous limestone as material Oviedo Cathedral (North Spain). provides good images samples: sedimentary...
Roofing slate from the town of Bernardos can be found in most buildings erected by Spanish monarchy 16 th to 19 centuries, making it a highly important component Spain's architectural heritage.The quarries are located outside Bernardos, 145 km north Madrid, Precambrian terrains Iberian Variscan Orogen.Although petrographic point view this rock is fact phyllite, for purposes construction known as roofing slate.Bernardos phyllite has set specific characteristics that make unique which clearly...
The main objective of this work is to test several nanoconsolidant treatments (pure Nano Estel, 1:1 diluted Estel and Tecnadis ZR-110), with the aim improving intergranular cohesion Novelda Stone. were applied in laboratory by capillary suction their effectiveness depth penetration have been evaluated on basis petrophysical characteristics stone (petrography, elemental physical properties, hydric properties ultrasound propagation), before after consolidation. Subsequently, order estimate...
The petrographical description and the values of some physical properties three rocks used in architectonic patrimony Catalunya are presented. These known, field "building stones" as Girona, Folgueroles Vinaixa stones. By ageing tests, their durability is predicted.
Las ocho explotaciones de rocas ornamentales existentes en Asturias a comienzos 2000 aprovechaban dos formaciones geologicas paleozoicas (Aman y Alba) una mesozoica (Lastres). En las primeras se extraian calizas, mientras que la tercera explotaban areniscas. Aqui presentan caracteristicas petrograficas (textura, mineralogia, etc.) fisico-mecanicas (densidad, porosidad, absorcion agua, heladicidad, resistencias cristalizacion sales, al choque, desgaste, compresion uniaxial flexion) dichos...
The term “roofing slate” comprises all natural rocks that can be used for roofing. Some of the characteristics define their performance as construction materials are water absorption, bending strength, mineral composition, and aesthetics. From a sustainability point view, roofing slates also have largest life expectancy lowest carbon emissions covering materials. This work reviews constructive slates, from technical data provided by producers over world. These data, supported petrological...
The petrographical characteristics of the principal types calcareous materials used in construction Seville Cathedral, as well some significant physical and deformational properties are presented. Artificial ageing tests were also carried out for evaluating weatherability those stones, both from monument corresponding quarries.
A review of some relevant papers about the cutting ornamental stones with diamond tools is presented here aim being useful to Natural Stone industries. Due length this paper, it has been divided in two parts: first one, influence factors equipments (machinery, disks, characteristics, etc) reviewed, and second next number journal, attention will be paid intrinsic rock characteristics that influences its cuttability and, thus, efficiency tools.
This paper follows another one published in the preceding number of this same journal, that reviewed some scientific papers on influence factors cutting equipments (machinery, characteristics, disks, etc) efficiency process ornamental rocks with diamond disks. In second part, inner rock characteristics (mineralogy, texture and voids) affecting performance are considered. Some classifications based their cuttability proposed by authors Institutions also reviewed.
Roofing slates are a category of building stones which have very distinctive feature: High fissility, allows them to be split into tiles that thin, regular and large. There several types roofing slates, depending on their lithology. The four main lithologies low-grade stricto sensu, phyllites, mica-schist. Occasionally, other rocks such as quartzites, serpentinites, or shales, can also used slates. must ensure waterproofing, quality depends both the rock installation. Installation therefore...
The application of fluorescence light microscopy in the textural study Portland cement clinker, specially its porosity, is presented. Principles and types technique are commented suggested sample preparation method described. use allows an easier clinker very proper images for automated quantification can be obtained. Besides, samples also observed by reflected-light polarizing microscopy.
