Fracture behavior of metakaolin‐based geopolymer reinforced with carbon nanofibers

open access: yesInternational Journal of Ceramic Engineering & Science, 2020
We investigate the fracture response of metakaolin‐based geopolymer reinforced with 0.1 wt%, 0.2 wt%, and 0.5 wt% carbon nanofibers. We measure the elastoplastic response using microindentation tests. We note an increase in indentation modulus of 5%, 13%,
