Nanotechnology has changed and will continue to change our vision, expectations and abilities to control the material world. These developments are going to play a massive role in the field of construction and construction materials. Carbon nanotubes (CNTs) are considered to be one of the most beneficial nano-reinforcement materials. The combination of high aspect ratio, small size, low density, and unique physical and chemical properties make them perfect candidates as reinforcements in multifunctional and smart cement-based materials. In the construction sector, attention and exploration in the field of carbon-based materials have been ongoing for many years. Although carbon fibers have already been applied to cementitious composites, carbon nanotubes (CNTs), as nanomaterials, have received widespread attention as a result of their unique multifunctional properties within the context of engineered materials, regarding both the mechanical and electrical properties of the composites.
