| Abstract (English): |
Stone materials, despite their great stability as construction materials, are not free from deterioration caused by nature, an effect that has been intensified by urban and industrial developments. Laser-induced breakdown spectroscopy (LIBS) is considered one of the most dynamic and promising techniques in the field of analytical spectroscopy. LIBS, which is performed in situ and is virtually non-destructive, offers a potential alternative to other techniques used in fields such as archaeology, preservation and restoration. In this work, the LIBS technique identifies key components and contaminants on the surface of the walls of the Convento y Basílica Menor de San Francisco de Asís, a historical building located in Old Havana, Cuba. The results are compared to previously performed analyses by X-ray fluorescence (XRF). [ABSTRACT FROM AUTHOR] |
| Abstract (Spanish): |
Los materiales pétreos, a pesar de la gran estabilidad que muestran como materiales de construcción, no están exonera- dos de la acción de la naturaleza en su deterioro, efecto que con el desarrollo urbano e industrial se han visto intensifica- dos. La espectroscopía de plasma inducido por láser (LIBS) es considerada como una de las técnicas más dinámicas y prometedoras en el campo de la espectroscopia analítica. LIBS, aplicable de forma in situ y prácticamente no destructiva, ofrece una alternativa potencial en relación a otras técnicas usadas en arqueología, conservación, restauración, etc. En este trabajo, haciendo uso de la técnica LIBS, a través un prototipo desarrollado, se determinan los componentes fundamentales presentes en la superficie de las paredes del Convento y Basílica Menor de San Francisco de Asís, construcción histórica, localizada en la Habana Vieja, Cuba. Así mismo se exponen posibles causas que estos elementos pueden ocasionar a la estructura pétrea. Los resultados son comparados con análi- sis realizados previamente por fluorescencia de rayos X (FRX). [ABSTRACT FROM AUTHOR] |
