| Sumario: | <strong>This article focuses on the identification of the used building materials and their most common degradation factors at the royal palace of king Farouk at Edfena, Rosetta, Egypt; and then assessing the most appropriate nano-consolidants for the decayed lime-based mortars at the palace, to achieve the target of this study; building materials were studied by means of XRD, FTIR spectroscopy and light optical microscope; in order to find out if there are any chemical decomposition or any physical failure. Halite salt was detected in the building limestone; mortars’ composition varies between lime and white Portland cement, while the plaster in the palace walls is a mixture of white Portland cement and lime. Plaster in the marina is a mixture of lime, white Portland cement and anhydrite. Pigment material in the green terrazzo is a mix of malachite and greenalite; portlandite abreast with brucite were found in the plaster and mortar mixtures in addition to clay minerals. Nanolime, nanotitanium, nanokaolin, nanosilica and multi-walled carbon nanotubes were used as consolidants, experimental study made it clear that nanotitanium and MWCNTs are the most appropriate consolidants in the current case study.</strong> |
