The Application of Nanotechnology in the Development of Concrete Coatings

In the current scenario, the search for new, more economical and environmentally sustainable approaches that contribute to the circular economy are receiving special attention in all sectors. In the construction sector, the most developed approach is the use of nanotechnology. It is one of the best and most innovative options available to improve performance in this sector. The continuous growth and increasing use of natural resources leads to the search for new materials that are more efficient, sustainable and increase the useful life of materials. In this sense, the use of nanomaterials as surface treatments is one of the fields of research that is evolving the most, since it is possible to prevent deterioration and improve the durability and conservation properties of construction materials, reducing restitution. This article conducts a capillary absorption test, which determines that the graphene oxide used as a protective treatment of the concrete surface decreases capillary water absorption by 15%; this is the beginning of a more exhaustive study to determine the effectiveness of this treatment and to be considered a nano-coating.
