THE MECHANISM OF SOME CONSOLIDATES MIGRATION IN POROUS STONE "LIME STONE".

The present paper is a result of investigation on migration of some consolidates - Thermoplastic resins to the surface pores of impregnated stone which are reported. The causes of migration were evaluated as well as the conditions which allow reducing these undesirable effects. It has been stated that the effect of resin molecules, solution viscosity, stone structure and the conditions of drying after impregnation. This investigation are applied on lime stone samples as a porous stone which widely used as building materials in Egypt. Different analytical and investigation methods were applied to study the stone samples such as polarizing microscope, X-ray diffraction analysis (XRD) and scanning electron microscope (SEM) equipped with (EDX) microanalyzer.
