N2 - Many efforts are underway to implement textile reinforced concrete (TRC) in real life constructions. TRC has many advantages over conventional methods, however the bonding between the concrete matrix and textile is not fully clear yet, which is the aim of the current work. In the present work, an interface coating strategy is adopted for textile surface modification, to improve the bonding between the carbon textile and cementitious matrix. The effect of coating schemes is systematically investigated by conducting pullout measurements of a single yarn from a concrete matrix, comparing modified surface coating yarns with plain and neat epoxy coated yarns. Further, the microstructure and interface of the modified textile and cementitious matrix also examined in detail by scanning electron microscopy. The developed method enhanced the bond strength by nearly two-fold.
