Textile-reinforced concrete (TRC) is a new innovative construction material that leads to lightweight and cost-effective construction. TRC consists of a finely grained cement-based matrix and high-performance, continuous multifilament yarns made of alkali-resistant glass, carbon, or polymer. Using these fibers provides superior mechanical properties and corrosion resistance in comparison with ferroconcrete. The application of epoxy resin coating to the textile materials improves the utilization of mechanical performance and handling properties as well. In recent years, researchers have studied alternative methods because coating process is very detailed and epoxy resin is of high cost. The experimental part of this chapter focuses on the experimental investigation carried out on high-strength concrete reinforced with hybrid yarns. Braiding technology was used to manufacture hybrid yarn from alkali-resistant glass fiber (ARG) and polypropylene (PP) filament. Next step, thermoplastic part of braided yarn was melted on press heating. Finally, TRC was produced from ARG, coated ARG, carbon fiber, coated carbon fiber, and heated hybrid yarns. Although the contribution of the heated hybrid yarn is limited, it is expected that the desired results will be obtained by changes in braiding yarn production and yarn composition ratios.

Textile-Reinforced Concrete (TRC) is a new construction material and has been used in civil engineering applications such as façade systems, sandwich panel and outside furniture during the past several decades. Generally in TRC, glass, carbon filaments, etc. are used to reinforce concrete because these high-performance filaments have superior mechanical properties and corrosion resistance. Coating of these filaments with different polymers provide extra performance for TRC’s durability. But, because of coating materials’ cost and stiffness, using of coating for TRC is not so advantageous. For these reasons, new approaches are needed. In this study, a new hybrid yarn design and production for TRC are emphasized. AR-Glass and polypropylene filament were used for production of hybrid yarn by commingling method. It was aimed to optimize the parameters of commingling yarn production with Taguchi orthogonal design. The experiments were performed by using L9 orthogonal matrix with respect to Taguchi approach. The best strength value in the study was obtained in production parameters where the machine production speed is 50 m / min, the air pressure is 6 bar and the feeding amount is 2%. Analysis of variance (ANOVA) and signal/noise ratio were used to evaluate the experiment results. As a result of the analysis, it has been observed that the machine production speed has the greatest effect on the breaking strength and the feed amount has the lowest effect.

Textile-reinforced concrete (TRC) is an innovative building material with areas of use such as sandwich panels, roof constructions, walking bridges and outdoor furniture, which are becoming increasingly common. TRC’s are composite structures consisting of concrete produced from fine-grained aggregate and textile structures with high tensile strength and non-corrosive. In the study, alkali resistant glass, basalt and carbon filaments, which are widely used in concrete reinforcement, were used as raw and epoxy resin coated on two different structures and in three different positions. 37 samples with different parameters were produced together with the non-reinforced sample and flexural test was applied to the samples. As a result of the flexural test, the highest value was obtained in carbon filament samples, while the lowest value was obtained in basalt filament samples. The contribution of the use of epoxy resin to the flexural strength compared to the use of raw filament was 63% in alkali resistant glass filament, 71% in basalt filament, and 127% in carbon filament.

Textile reinforced concrete (TRC) is an innovative building material that has been used in recent years and consist of textile components with high tensile strength and concrete produced from finegrained aggregates. Textile components can be used in the form of raw yarn, coated with various polymers, and recently, in the form of hybrid yarn. There are many hybrid yarn production methods used in the textile industry, and in this study, the braiding technique, which is suitable for the material used, is emphasized. In the study, samples were produced by positioning two different textile surfaces produced from three different yarn structures with carbon roving in three different positions in the concrete. Compared to the raw filament use, it was observed that the flexural strength increased by 23% with the use of hybrid yarn, while it increased by 167% with the use of epoxy coated filament.
