Cement-Based Composites Containing Carbon Nanofibers and Carbon Nanotubes

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. Results: 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 . Recommendation: some projected future investigations were indicated.
