Abstract
Stone, which composes of monuments, has been damaged by natural and artificial weathering. The physical damage in stone monuments could make the rate of weathering accelerate and lead to further damage. Therefore it is important to increase the stability of stone, which is used in monument, in order to conserve the stone monuments and the consolidation is evaluated as one of the most effective conservation treatments. For the purpose to analyze the effect of the consolidation with ethyl silicate resin in Sphinx of Giza, Mokkatam limestone, which has similar properties to the stone used in Sphinx, is used as a sample in this study. As a result of the research, water absorption rate and permeability in Mokkatam limestone decrease, but the ultrasonic velocity increases after consolidation. In the analysis of digital image of Mokkatam limestone, the color of the stone surface is darkened after consolidation. But the degree of the color change is small, so it is evaluated that the change could be ignored.
