Bioactivity and mechanical properties of White Portland cement paste with carbon nanotubes

The aim of this research work was to investigate the mechanical properties and bioactivity of White Portland cement paste which added carbon nanotubes in order to improve compressive strength property. The current results found that enhanced compressive strength of white Portland cement paste was found when carbon nanotubes were added 1% by weight and can achieve compressive strength of 51.34 MPa after curing in water bath for 7 days. Moreover, a formation of hydroxyapatite was also exhibited on both control mix and white Portland cement paste with added carbon nanotubes.
