Review of research progress on carbon nanotubes modified cementitious composites

Carbon nanotubes(CNTs) are drawing widespread attention due to the unique structure and excellent properties, such as the mechanical property and the electrical property. It will significantly improve the cement-based composites' properties when adding CNTs into composites. The CNTs' basic properties and dispersion methods, and elucidated the properties of cement-based composites recombining CNTs, including the mechanical property, the deformation property, the durability property, the thermal conductivities, electrical conductivities and microwave absorbing properties were briefly introduced. The problems existing in present research were also summarized, and some proposes for future study were given.
