Recent Progress in Nanomaterials for Modern Concrete Infrastructure: Advantages and Challenges.

Modern concrete infrastructure requires structural components with higher mechanical strength and greater durability. A solution is the addition of nanomaterials to cement-based materials, which can enhance their mechanical properties. Some such nanomaterials include nano-silica (nano-SiO), nano-alumina (nano-AlO), nano-ferric oxide (nano-FeO), nano-titanium oxide (nano-TiO), carbon nanotubes (CNTs), graphene and graphene oxide.
