Construction Innovation - Graphene Oxide as the Differentiating Nanoadditive for Concrete and Coatings

Abstract:

When discussing graphene materials, their mechanical strength, impermeability, flexibility, thermal and electrical conductivity, and lightness are key reference points, earning them the moniker "all-in-one material. “This versatility makes graphene suitable for various applications, including electronics, medicine, plastics, coatings, construction, and renewable energies. However, it's crucial to note that the behavior of these materials at the nanometric scale depends on factors such as the type of graphene, functionalization, concentration, and the specific processes involved in each industry. Since the isolation of graphene in 2004, significant efforts have been made to comprehend its multifunctional properties. Nevertheless, the primary challenge lies in translating this knowledge from the laboratory to industrial applications, hampered by the high cost and low yield of graphene. Fortunately, the construction industry, particularly the concrete and coatings sector, appears to be one of the most promising fields for the integration of this nanotechnology. In this context, we present a diverse array of representative trials conducted on various concrete designs and environmentally friendly, antimicrobial, and anticorrosive coatings enhanced with graphene materials. These trials showcase the multifunctional enhancement of properties thanks to the incorporation of graphene materials in different commercially available products tailored for industrial applications, demonstrating that graphene not only represents a technological innovation but is also a catalyst for more sustainable practices in various industries. Its ability to improve the efficiency of different products and applications, becomes graphene as a key material in the immediate future with which industries operate within ecological limits while meeting human needs.
