Abstract: The mechanical performance of textile reinforced concrete (TRC) thin-plate under high temperature conditions was investigated using three-point bending tests. The influence of polypropylene (PP) fiber addition on the out-of-plane load capacity of TRC thin-plate after high temperature treatment was also studied. The results showed that the thermostability of TRC thin-plate with textile impregnated with epoxy resin was not good, but that the out-of-plane load capacity of TRC thin-plate after high temperature treatment could be improved by increasing the plate thickness or the textile distribution rate. Under normal temperature and a high temperature of 120 °C, the out-of-plane load capacity of specimens could be increased and cracks better distributed by mixing the TRC with PP fiber. However, the out-of-plane load capacity of TRC thin-plate under a continuous high temperature of 200 °C was not much affected by the addition of PP fiber. The result of a microcosmic scanning electron microscope (SEM) test showed that the main reason for the interfacial adhesive failure between the textile and the original concrete substrate was the degradation of the epoxy resin under high temperature.
