This research investigates the effect of incorporating conventional and functionalized carbon nanotubes into a cementitious matrix made of 30% cement and 70% fly ash with high amounts of sulfate. Carbon nanotubes were added in different proportions, and the mechanical and physical properties were evaluated through a compressive strength and minibar test, respectively. The results showed that carbon nanotubes improve the compressive strength up to 17% and the expansion is reduced by 10 times. This research is novel because application of carbon nanotubes in hybrid alkaline pastes with fly ash that contain high amounts of sulfate has not been investigated before.
