Abstract
Textile reinforced concrete (TRC) has gained attention as a viable alternative to conventional reinforced concrete due to its improved mechanical properties and design adaptability. Despite significant research into the mechanical properties of TRC, studies regarding the flexural effect of pre-stretching with different numbers of textile reinforcements are currently limited. Therefore, this research focuses on assessing the flexural characteristics of TRC panels with the incorporation of mesh pre- stretching. Additionally, the study compares the flexural behaviour between alkali-resistant (AR) glass fibre TRC and carbon fibre TRC. A three-point bending test was conducted to assess the flexural behaviour of TRC, investigating the impact of the number of textile layers and the application of pre-stretching on flexural strength and post-cracking stiffness. The findings, exhibited by the flexural stress vs. displacement curve, indicate that applying pre-stretching to carbon fibre TRC effectively increases the flexural strength of carbon textiles and enhances post-cracking stiffness. Moreover, the greater the number of carbon textiles, the higher the flexural stress of the specimens, provided the textiles are placed in the tensile zone. Nevertheless, when comparing carbon fibre TRC with AR glass fibre TRC, it is found that the increase in flexural strength is more significant for carbon fibre TRC. Overall, applying pre-stretching to carbon fibre significantly improves the TRC's flexural performance, specifically during the post-cracking stage and in crack distribution. Furthermore, due to the higher elastic modulus and tensile strength of carbon fibre, TRC reinforced with carbon textiles shows greater flexural strength and ductility compared to AR glass fibre TRC.
