CHARACTERISATION OF MATERIALS FOR THE EMERGENCY WORK IN THE CONVALESCENT WARD OF THE HOSPITAL REAL (GRANADA)
Close to the Triumphal Gardens, the Royal Hospital of Granada is the current seat of the Rectorate of the University. It was built at the beginning of the 16th century and at the end of the 20th century, the Hospital became part of the university heritage. This intervention was carried out on the Convalescents Room, which is on the third floor, open to the outside and facing the Triunfo Gardens.
For this project, a series of samples of stone material and mortars from the north-east wall of the Convalescent Ward were analysed using X-ray diffraction (XRD) and polarised optical microscopy (POM) to determine their compositional and morphological characteristics. On the other hand, its porosimetry was determined by mercury intrusion (PIM), its compressive strength (DRC), real and apparent density (DDRA). Finally, a granulometric analysis was carried out by sieving (AG), as well as the content of organic matter (CMO) and carbonates (CCA), and an estimation of mechanical resistance (ERES) was made. In a second phase, almost all the previous tests were repeated and a determination of the open porosity of the stone material (DPA) was also carried out. In a new phase of the project, a new sample of reddish stone material from the external area and a yellowish one from the internal area of the wall under study were characterised. For this, XRD, MOP, loupe-videomicroscopy (VM) and again DRC were used. For the last phase, the mechanical resistance of a mortar and a natural hydraulic lime were studied to determine their suitability as materials for the subsequent restoration of the Convalescent Room.
