Interfacial bonding performance of textile reinforced ECC and seawater sea-sand concrete under a dry-wet environment

•The bonding properties between TRE and SWSSC under dry-wet cycles were studied.•The factors influence the bonding properties between TRE and SWSSC were investigated.•The average bond strength, load-slip curves and interfacial fracture energies were analyzed.•The fracture energies with different TRE thicknesses have different changing patterns.
