12 - Conclusion: the role of carbon nanotubes and nanofibers in concrete technology

Abstract

Carbon nanotubes and carbon nanofibers are relatively new materials, whose use has steadily increased in various applications over the past few decades. The electronic and pharmaceutical industries are currently the main players, but the construction industry, especially the mass production of concrete, is following closely behind. Concrete is an excellent construction material, but often suffers due to problems with durability and sustainability. As shown in this book, nanomaterials can address both of these issues by enhancing the mechanical and physical properties of concrete, and enabling self-monitoring and energy-harvesting capabilities. However, a big question remains as to whether these nanomaterials are safe to be used in mass quantities when incorporated into concrete. This chapter summarizes data, conclusions, and questions gathered for this book and indicates advantages, risks, and roles of both materials in concrete technology.
