Textile Reinforced Cementitious (TRC) composites have gained recent ttention due to several advantages compared to traditional steel-reinforced concrete, such as concrete usage reductions and design freedom. The mplementation of this technology on a sandwich design offers light-weight nd slender structural elements with superior mechanical performance. espite their advantages, they exhibit a complicated structural and fracture attern rendering their monitoring essential, as only detailed information on the damage modes will lead to understanding their failure behaviour. This review paper reports on NDTs application, working principle and configuration, performance and accuracy. Potential future lines of research and advances are discussed.
