摘要：The paper reports the formulation of a new lime plaster on the basis of the chemical and mineralogical characterization of the plasters of Sindhudurg Fort in western India. The plaster samples extracted from the fort’s walls and mount were studied using petrological microscope, X-ray fluorescence Spectroscopy (XRF), X- ray diffraction studies (XRD), Fourier Transform infrared Spectroscopy (FTIR), scanning electron microscope (SEM), and thermal analysis. The granulometric analysis indicates that the plasters were prepared by mixing coarse to medium grained sands that clearly show fracture pointing towards mechanical mixing. The FTIR spectrum of the plaster indicates atomic disorder in the anthropogenic calcite crystals. Thermal analysis shows presence of re-carbonated lime as part of the binder is perfectly crystallized. Compact microstructures were observed under SEM with aggregates well embedded in the matrix. Thermal analysis of the plaster shows presence of re-carbonated lime as part of the binder is perfectly crystallized. Compositional similarities were noted between the mount and fort wall lime plasters, which were prepared by mixing aggregates of basaltic origin with varied grain size and shape. The present study is a holistic approach to prepare compatible plasters required for the restoration of the site and similar nearby monuments.
