“…The dimensions of the beams, which are 340 mm long, 100 mm wide, and 15 mm thick, were determined in accordance to DIN EN 1170-5:1997. Schematic layout of the beams is given in Perry et al (2020) and here again, in Figure 3, for the completeness of the study. A single textile layer was located 5 mm from the lower face of each beam.…”

“…It significantly influences the structural response (e.g. Banholzer, 2004; Barhum and Mechtcherine, 2012; Bentur et al, 2010; Hartig et al, 2008; Hegger et al, 2006; Perry et al, 2020; Soranakom, 2008), and ultimately reflected by changes of their electrical characterization during wetting events (Goldfeld and Perry, 2018, 2019).…”

“…From the structural response point of view, an enhanced structural performance is achieved by improving the textile impregnation and the bonding between the textiles and the cementitious matrix. It is achieved by using different binding configurations (Hegger and Voss, 2008; Peled and Bentur, 2003; Peled et al, 1999; Quadflieg et al, 2017; Stolyarov et al, 2015), applying pre-treatment procedures such as coating (Gao et al, 2004; Hegger et al, 2006), combining binding and coating (Perry et al, 2020), or by improving the penetrability of the cementitious matrix (Brockmann, 2007). However, from the sensory point of view it was found (Goldfeld and Yosef, 2019) that coating eventually limits the sensory capabilities in case of monitoring the exact structural state and the severity of cracks.…”

The study investigates the capabilities of various configurations of self-sensory carbon-based textiles to detect and distinguish between the severity of water infiltration through cracked zones along textile reinforced concrete (TRC) elements. The investigation aims to explore whether an optimal smart textile configuration can improve the structural performance while providing sensitive sensory capabilities. Such an investigation is needed for the development of intelligent TRC structures. Specifically, the study experimentally investigates the effect of two types of bindings and the effect of coating on the mutual structural-sensory performances. The sensory concept is based on changes of the electrical mechanism of two adjacent carbon rovings due to infiltration of water through cracked zones. Eight TRC beam samples were cast and mechanically loaded up to cracking. The cracked zones were monitored, and each zone was separately examined by performing a wetting event. It is demonstrated that the type of binding and coating, which significantly affect the structural response, reflect and affect the measured electrical signal. It is found that there is a tradeoff mechanism between the structural response and the sensory capabilities. While specific textile configuration improves the structural performance, it may reduce its sensory capability to distinguish between the magnitude of water infiltration.
