Abstract
Abstract Textile reinforced mortars (TRM), also known in the international literature as textile reinforced concrete (TRC) or fabric reinforced cementitious matrix (FRCM) materials, have been widel...
Highlights
Over the last decades, the issue of upgrading existing structures has been of great importance because of their deterioration, ageing, environmental induced degradation, a lack of maintenance, or the need to meet current design requirements
The Fiber reinforced polymers (FRP) strengthening technique has a few drawbacks, which are mainly associated with the use of epoxy resins—namely, high cost, poor performance in high temperatures, inability to apply on wet surfaces, and incompatibility with substrate materials
Despite the fact that the effectiveness of the textile reinforced mortar (TRM) jackets was dramatically improved [up to 500% based on the results presented in Tzoura and Triantafillou (2016)], an anchorage system with metallic components may be susceptible to corrosion and its use may result in tearing failure of the textiles due to stress concentrations
Summary
The inorganic matrix is not classified as concrete, because of the very small size of aggregates. This paper provides a comprehensive state-of-the-art review on the use of TRM systems for strengthening with a focus on concrete members or structures; it covers a broader range of applications compared to the recent study of Awani et al (2017) It provides a critical review of more than 100 past studies and enables readers to identify gaps in the existing literature that could be investigated in future work. Coating the textile material resulted in a bond capacity increase and a change in the failure mode from slippage of fibers through the mortar to TRM debonding at the textile–mortar interface. Raoof and Bournas (2017c) investigated the bond between TRM or FRP and concrete substrate at high temperatures by conducting double-lap direct shear tests. In the case of TRM specimens, cohesive failure was observed over all tested temperatures (20°C–400°C)
