“…At the tip of the fiber end, uneven tear and end splitting of small BF fiber strands were observed which indicated that the fiber greatly suffered large stress during the pullout process. Similar finding was reported by Chindaprasirt et al [37] where glass fiber with bundle type was found to exhibit better bonding and strong interfacial bond.…”

“…In practice, the properties of cementitious matrix can be enhanced using property enhancement additives. For example, phase change materials can be used to improve thermal storage [23][24][25][26][27][28], crumb rubber can be used to improve energy absorption [29][30][31][32], or nanomaterials can be used to improve mechanical properties [33][34][35][36][37] etc.…”

“…In general, the performance of FRC can be accessed through the standard tests such as ASTM C1609 38, ASTM C1399 39 or JSCE SF4 [40] which are based mainly on flexural testing. However, in order to investigate the fiber-matrix interaction, a so-called single fiber pullout test is more appropriated [37,41,42]. The graphene oxide (GO) solution was produced at a concentration of 10 mg/ml.…”

In this study, the influence of graphene oxide nanoparticles on the bond-slip behavior of fiber and fly ash based geopolymer paste was examined. Geopolymer paste incorporating graphene oxide nanoparticles solution was cast in half briquetted specimens and embedded with a fiber. Three types of fibers were used: steel, polypropylene, and basalt. The pullout test was performed at two distinct speeds: 1 mm/second and 3 mm/second. Results showed that the addition of graphene oxide increased the compressive strength of geopolymer by about 7%. The bond-slip responses of fibers embedded in geopolymer mixed with graphene oxide exhibited higher peak stress and toughness as compared to those embedded in normal geopolymer. Each fiber type also showed 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 which showed no-slip in pull out responses. Both bond strength and toughness were found to be rate sensitive. The sensitivity was higher in graphene oxide/geopolymer than in conventional geopolymer.
