چکیده

Nowadays, due to the increasing population and the expansion of urbanization, and consequently the need for high-rise and multi-storey buildings that , the safety and resistance of the load bearing members of the structures has become of interest to researchers. For this purpose, different approaches have been proposed, including nanomaterials as a suitable and optimal method. Using nanomaterials as a percentage of cement weight improves concrete performance and increases its strength. Since these materials should be used at the beginning of concrete construction, therefore, they cannot be used in constructed structures. But a protective coating containing these nanomaterials can enhance and improve the performance of the structures, which is applicable to the fabricated structures. The purpose of this study was to investigate the effect of protective coatings with Nano silica, carbon nanotube and graphene  nanomaterials. For this purpose, four thicknesses different and 2% nanomaterials different, the effect of thickness and percentage of nanomaterials were investigated. The results show that the sample containing 15% of silica with 26.74 N/mm² has the highest effect compared to other nanomaterials. However, due to the low percentages of carbon nanotube and graphene, these materials have a significant effect.
