Carbon Nanotubes (CNT) in Construction Material Reinforcement

Printer-friendly versionPDF version

Carbon Nanotubes (CNTs) are incredibly strong hollow strings of carbon atoms that bond together in a tube or pipe-like fashion with unique properties which can be added to a multitude of materials to enhance durability or strength.  CNTs could potentially be added to concrete or asphalt in a similar fashion to the way rebar reinforcement is used in modern construction, greatly increasing the structural strength and longevity of roads, foundations, load-bearing columns and walls, etc.
