Abstract
Methods for the dispersion and synthesis of multi-walled carbon nanotube-cement composites with high concentrations of multi-walled carbon nanotubes that do not require chemical dispersion aids or dispersion-enhancing chemical surface functionalization are provided. Also provided are multi-walled carbon nanotube-cement composites made using the methods. Methods for the dispersion and synthesis of carbon nanofiber-cement composites with high concentrations of carbon nanofibers that do not require chemical dispersion aids or dispersion-enhancing chemical surface functionalization are further provided. Also provided are carbon nanofiber-cement composites made using the methods.
