Abstract
In cement-based composites, carbon nanotubes (CNTs) and carbon nano fibres
(CNFs) can act as crack bridging, delaying the development of nano fractures into microcracks.
Recent research on the use of CNTs and CNFs in cement-based composites was reviewed in
this paper. Earlier studies have demonstrated that cement-based composites reinforced with
CNTs/CNFs have lower porosities and superior mechanical properties to plain cement-based
composites. Using CNTs or CNFs in cement-based composites presents challenges due to their
low matrix dispersion and weak interfacial contact. Some projected future investigations were
indicated.
