[EN]The constituent materials used to build the wooden vault over the Plenary Hall in the Spain’s Senate Building (ca 1814-1820) are analyzed in this paper. Characteristics of gypsum mortar applied on pine beams, boards and blockboard, have been determined. The esparto (=needlegrass) fibre provides a framework for the gypsum mortar to ensure adhesion and forming the surface of the dome. Physical-mechanical properties of the burnt clay-lightened gypsum mortars were determined with laboratory tests, while the composition of these materials was found with XRD,SEM and IR.
[ES]En este artículo se analizan los materiales de la bóveda encamonada que cubre el Salón de Plenos del Senado de España (hacia 1814-1820). Se han determinado en particular las características físico-mecánicas del mortero de yeso aplicado sobre vigas, tablas y enlistonados de madera de pino, entomizados con fibra de esparto para asegurar la adherencia y conformar la superficie de la bóveda. Con los análisis de DRX, SEM e IR, se ha completado la caracterización del mortero que presenta adiciones de cerámica cocida.
