In this study, cheap nanoparticles with the highest hybrid similarity were introduced to increase the surface resistance of ancient Pasargadae (Cyrus Tomb) rocks. As result, the kind of mineral of thin section of sample was detected as calcite and grainstone texture. The physical features of the sample indicated a high porosity. In order to achieve a high compatibility of the intended Nano materials, some powder of the sample was used as pre-material through Mechanical Grinder. After preparation of the powder, Nano material was prepared due to sol-gel method. Calcium Titanate blurs with the phase of Perovskite and Titanium dioxide with the phase of Anatase have been detected as XRD. These compounds were confirmed by FT-IR. The size of spherical and oval blurs prepared in the scale of Nano was confirmed by SEM. The existence of common elements such as Calcium, Titanium, Oxygen and Carbon was detected as EDX spectrometer. In this experience, Ethanol was used as solvent. In 4 hours, the gained Colloidal dissolved was added on the surface of the stone by the capillary specific. So as to module the resistance of the sample, the coated surface was examined under the abrasion test. Along with these experiments, all the levels for pre-material lime were done. The results show a relative improvement in the surface resistance of the sample rock. Meanwhile, there wasn’t any remarkable change in the case of the color of the sample.
