摘要

Textile-reinforced concrete (TRC) is an innovative high-performance composite material that can be both used for strengthening existing structures or development of load-bearing components. Despite a growing body of research in the field of TRCs, the mechanical performance of these composites is not completely understood yet. Aiming to provide further insights into flexural performance of TRCs, this paper is focused on the effect of number of textile layers without concrete layers between the reinforcement layers on the bending performance of TRCs plate by conducting four-point bending tests on four different configurations. Flexural stresses are noticeably increasing as the number of basalt layers increases. A rise in the layer count of basalt textile allows for a greater number of cracks with reduced spacing. Moreover, Increasing the layers of textiles enhances toughness by resisting crack widening, promoting distributed micro-cracks, and improving ductility, allowing the structure to sustain greater deformations before failure. The results presented will help in better understanding the flexural behaviour of TRCs and developing suitable design relations when multiple layers of reinforcement are used.
