WebApr 1, 2024 · At normal temperatures, the CNT-enhanced concrete has a much better load capacity and ductility properties thanks to the CNT-calcium silicate hydrate interface. This interface enables the flexible properties of the CNT to have a greater impact across the composite, increasing the concrete’s ductility and flexural strength. WebThe tensile strength of carbon nanotubes is approximately 100 times greater than that of steel of the same diameter. There are two things that account for this strength. The first is the strength provided by the interlocking carbon-to-carbon covalent bonds. The second is the fact that each carbon nanotube is one large molecule.
