Geopolymer paste incorporating a graphene oxide nanoparticle solution was cast in half briquetted specimens and embedded with a fiber. Three types of fiber were used: steel, polypropylene, and basalt. The pullout test was performed at two distinct speeds: 1 mm\/s and 3 mm\/s. The results showed that the addition of graphene oxide increased the compressive strength of the geopolymer by about 7%. The bond-slip responses of fibers embedded in the geopolymer mixed with graphene oxide exhibited higher peak stress and toughness compared to those embedded in a normal geopolymer. Each fiber type also showed a different mode of failure. Both steel and polypropylene fibers showed full bond-slip responses due to their high ductility. Basalt fiber, on the other hand, because of its brittleness, failed by fiber fracture mode and showed no slip in pullout responses. Both bond strength and toughness were found to be rate-sensitive. The sensitivity was higher in the graphene oxide\/geopolymer than in the conventional geopolymer.<\/jats:p>","DOI":"10.3390\/nano12060943","type":"journal-article","created":{"date-parts":[[2022,3,13]],"date-time":"2022-03-13T21:44:17Z","timestamp":1647207857000},"page":"943","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":30,"title":["Influence of Graphene Oxide Nanoparticles on Bond-Slip Reponses between Fiber and Geopolymer Mortar"],"prefix":"10.3390","volume":"12","author":[{"ORCID":"https:\/\/orcid.org\/0000-0002-8366-6603","authenticated-orcid":false,"given":"Darrakorn","family":"Intarabut","sequence":"first","affiliation":[{"name":"Construction and Building Materials Research Center, Department of Civil Engineering, Faculty of Engineering, King Mongkut\u2019s University of Technology North Bangkok, Bangkok 10800, Thailand"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-9580-7063","authenticated-orcid":false,"given":"Piti","family":"Sukontasukkul","sequence":"additional","affiliation":[{"name":"Construction and Building Materials Research Center, Department of Civil Engineering, Faculty of Engineering, King Mongkut\u2019s University of Technology North Bangkok, Bangkok 10800, Thailand"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Tanakorn","family":"Phoo-ngernkham","sequence":"additional","affiliation":[{"name":"Sustainable Construction Material Technology Research Unit, Department of Civil Engineering, Faculty of Engineering and Architecture, Rajamangala University of Technology Isan, Nakhon Ratchasima 30000, Thailand"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-5262-6476","authenticated-orcid":false,"given":"Hexin","family":"Zhang","sequence":"additional","affiliation":[{"name":"School of Engineering and the Built Environment, Edinburgh Napier University, Edinburgh EH14 1DJ, UK"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Doo-Yeol","family":"Yoo","sequence":"additional","affiliation":[{"name":"Department of Architectural Engineering, Hanyang University, Seongdong-gu, Seoul 04763, Korea"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Suchart","family":"Limkatanyu","sequence":"additional","affiliation":[{"name":"Department of Civil Engineering, Faculty of Engineering, Hat Yai Campus, Prince of Songkla University, Songkla 90110, Thailand"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Prinya","family":"Chindaprasirt","sequence":"additional","affiliation":[{"name":"Sustainable Infrastructure Research and Development Center, Department of Civil Engineering, Faculty of Engineering, Khon Kaen University, Khon Kaen 40002, Thailand"},{"name":"Academy of Science, Royal Society of Thailand, Dusit, Bangkok 10210, Thailand"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"1968","published-online":{"date-parts":[[2022,3,13]]},"reference":[{"key":"ref_1","doi-asserted-by":"crossref","first-page":"2917","DOI":"10.1007\/s10853-006-0637-z","article-title":"Geopolymer technology: The current state of the art","volume":"42","author":"Duxson","year":"2007","journal-title":"J.
