Abstract:
Textile-reinforced concrete (TRC) offers a solution to the drawback associated with the production of cement and
its use in construction. It also promotes the design of concrete in a post-cracking stage as the yarns bridge cracks
once the concrete fails in tension. The pull-out behaviour of TRC has and still receives considerable attention to
progress its use, but the full extent and types of mechanisms associated with the pull-out is not yet fully understood.
This research sets out to investigate the pull-out mechanism when considering various embedment
lengths, as well as employing the use of X-ray computed tomography and scanning electronic microscope imaging
on the post-pull-out elements. The study identified a bottleneck mechanism, resulting from the undulating
imprint the warp yarn produces, which improves the pull-out resistance of yarns. Additionally, the latter
mentioned mechanism is also enhanced by the effect of congestion caused by filament debris, resulting from the
telescopic failure.
