En este estudio se informa sobre la caracterización química de un revestimiento de mortero de cal espeso en un método de construccíon de muros en Filipinas llmado tabique Pampango, o método de acacia y barro. El material de embadurnamiento de un convento de la iglesia del período colonial Español del siglo XIX en Loboc, Bohol, se analizó mediante flourescencia de rayos X (XRF), difracción de rayos X (XRD), espectroscopía infrarroja por transformada de Fourier (FTIR), análisis termogravimétrico (TGA) y analisis granulometrico. Estos análisis demuestran que el material de embadurnamiento comprende un aglutinante principalmente calcítico con minerales arcillosos presentes de forma natural en la materia prima o suelos arcillosos añadidos intencionalmente. La presencia de minerales arcillosos hizo que el aglutinante fuera hidráulico o se endureciera mediante la adición de agua. Los agregados de tamaño fino abundan en el material de embadurnamiento, lo que lo hace adecuado para aplicaciones que no soportan carga. Este estudio proporcionó una base química sobre las técnicas de construcción empleadas durante el período colonial en Filipinas que es útil para promover el trabajo de conservación y el conocimiento histórico local.

Jan-Michael Cayme, Chemistry Department De La Salle University, Manila Philippines

Jan Michael C. Cayme is an assistant professorial lecturer at the Chemistry Department of the De La Salle University, Manila, a licensed chemist in the Philippines, holder of a Masters’ Degree in Chemistry and completing a Ph.D. in Chemistry at the University of the Philippines, Diliman. He has several peer-reviewed publications in local and international scientific journals on the chemical analysis of colonial period-built materials in the Philippines. As a faculty member of the Chemistry Department at the De La Salle University, Manila, and The Graduate School of the University of Santo Tomas, he initiated the teaching of advanced analytical chemistry techniques with a focus on cultural heritage for chemistry majors and a general scientific approach to chemistry and cultural heritage for non-science majors. He is also a former field cultural researcher of the Institute of Philippine Culture at the Ateneo de Manila University, documenting the architectural styles and history of pre-World War 2 structures in Metro Manila.
