Abstract

Nano-lime dispersed in propanol was extensively used for consolidation of mural paintings. Current result pointed out the effect of using different nano-dispersed materials (nano silica, nano calcium hydroxide and carbonate) with Beva 37 soluble in toluene/ethanol to consolidate models of an Egyptian Coptic fresco. Scanning electron microscope (SEM), X-ray diffraction (XRD), Fourier transform infrared spectroscopy (FT-IR) and spectrophotometer were used to determine the visual properties, morphological and physical properties of the treated models. The influence of treatment on various mechanical characteristics of consolidated models were also, tested in detail by means of tests on specimens of the treated models. The treatment was carried out in presence of the nano-materials with or without the polymeric material. The mechanical characteristics of the treated models were improved. This can be attributed to nano-calcium hydroxide was turned into calcium carbonate and both of nano- silica and nano-calcium carbonate appeared as filler. The high impact of nano-materials remind even in presence of polymeric material (Beva 371).
