Characterization of ancient, byzantine and later historic mortars by thermal and X-ray diffraction techniques

The Role of Restoration Mortars in the Earthquake Protection of Kaisariani Monastery

“…Differential Thermal and Thermo-Gravimetric Analysis (DTA-TG) provides qualitative and quantitative information regarding the composition of the samples (Mettler Toledo 651e). The temperature range applied was 25-1000 o C and the heating rate was selected at 10 o C/min [17]. X-ray diffraction (XRD) provides information regarding the mineralogical composition of the materials (Advance D8 Diffractometer of Bruker Corporation) [16][17][18].…”

X-ray diffraction (XRD) provides information regarding the mineralogical composition of the materials (Advance D8 Diffractometer of Bruker Corporation) [16][17][18]. The microstructural characteristics of the samples were studied through the use of Mercury Intrusion Porosimetry (MIP) with the use of a Pascal 400 Thermo-Electronics-Corporation [16,19].…”

Caracterización de morteros mudéjares de la iglesia de San Gil Abad (Zaragoza, España): Investigación de la tecnología de fabricación de morteros históricos de yeso

“…The samples show at least two exothermic events; a sharp exothermic peak at around 250 ºC could correspond to the beginning of the transition of anhydrite III to anhydrite II, whereas exothermic reactions produced in mortars in the range 300-500 ºC attributed to either the dehydroxilation of clay compounds or the presence of organic matter in the mortars according to (23).…”

Metodología para la intervención en elementos históricos: el caso de la espadaña del convento de Nuestra Señora de la Consolación (Alcalá de Henares-Madrid-España)

“…Moropoulou, en (20) presenta el ratio CO 2 /H 2 O (agua hidráuli-ca), que representa el inverso de la hidraulicidad de la muestra, frente al CO 2 (pérdida de peso en %) extraídos de los resultados del ATD, considerando que permite discernir entre diferentes tipologías de morteros (20) (14). Los resultados de la muestra en estudio se han tratado junto con los expresados en (20) y normalizados a la cantidad de binder presente en la muestra (Figura 9).…”
