High Temperature Effect on Concrete Confined Through Textile Reinforced Mortar
摘要
This study investigates the impact of high temperatures on concrete confined with Textile Reinforced Mortar (TRM) also known as FRCM (Fabric Reinforced Cementitious Matrix), or TRCC (Textile Reinforced Cementitious Composites). High temperatures pose significant challenges to the structural integrity and durability of concrete, particularly in fire-exposed environments. The confinement of concrete using TRM, a composite material consisting of textiles embedded in a cementitious matrix, offers a promising solution to enhance the performance of concrete under such conditions. The research involved subjecting TRM-confined concrete specimens to varying high temperature regimes, followed by comprehensive mechanical testing to evaluate residual strength, stiffness, and failure modes. Results indicate that TRM confinement significantly improves the residual strength concrete exposed to high temperatures, maintaining higher levels of structural integrity compared to unconfined specimens. TRM confinement can be an effective method to enhance structural reliability of concrete structures and provides important data for engineering applications in fire-prone areas. The findings contribute to the development of safer, more resilient infrastructure, highlighting the importance of incorporating advanced composite materials in modern construction practices to mitigate high-temperature effects on concrete.
