Abstract:Textile-reinforced concrete (TRC), which has superior crack- and corrosion-resistance capacity, is a type of available inorganic repairing material. However, TRC is still undefined in terms of its interfacial performance between it and existing concrete under marine erosion environments. In this paper, a double-side shear test was used to study the effect of TRC precracking, concrete strength, interface form, short-cut fiber, and freezing-and-thawing cycle number on the interfacial bond properties between TRC and existing concrete under chloride salt erosion and freezing-and-thawing cycles. The results indicate that the shear capacity can be improved by increasing the concrete strength, roughening the reinforced interface, and adding short-cut fibers into the TRC. In addition to that, proper precracking in TRC can also improve the interfacial properties; however, increasing the precracking of TRC to a certain extent will decrease the interfacial properties. In addition, as freezing-and-thawing cycles increase, interfacial properties between TRC and existing concrete will decrease, obviously without serious deterioration in the TRC layer. Therefore, TRC has the potential application of repairing and enhancing existing concrete structures under a harsh freezing-and-thawing environment.
