Influence of Fabric Manufacturing Techniques on the Tensile Capacity of Textile Reinforced Concrete (TRC)
摘要
Conventional steel reinforcement susceptibility to corrosion adversely effects sustainability of reinforced structures. Advanced materials such as textile-reinforced concrete (TRC), with their high tensile strength, corrosion resistance, lightweight properties, and potential for low-emission construction solutions, are becoming increasingly interesting in the realm of reinforced concrete. A range of test setups are employed to characterise the mechanical properties of textile-reinforced concrete, yet the influence of differing setup realisations on mechanical performance remains uncertain. A round robin test series was conducted to evaluate the accuracy and precision of measurement methods across participating laboratories, identify discrepancies in results, and enhance the reliability and comparability of test outcomes. Concrete specimens were reinforced with basalt and carbon textiles which were manufactured using different methods, namely (a) warp knitting and (b) tailored fiber placement (technical embroidery. In total 20 specimens per each lab were subjected to uniaxial tensile to evaluate mechanical properties. The results reveal a high accuracy of already established setups to determine uniaxial tensile response of TRC.
