An Investigation of the Properties of 3D Textile-Reinforced Cementitious Composite Exposed to High Temperature

The 3D textile-reinforced cementitious composite applications have various and large area of utilization. The studies have been performed on the 3D spacer fabrics, and its applications are especially on the improvement of the mechanical properties of the fabrics. However, the durability properties of the 3D spacer fabrics are also important for the 3D spacer fabric applications. Due to the lack of studies on this subject, this research attempts to investigate the performance of 3D textile-reinforced cementitious composite under elevated temperature. For this purpose, 3D textile-reinforced cementitious composite specimens were exposed to 150, 200, and 300 degrees C temperatures for two hours. Tensile and flexural tests were performed for determination of the performance of 3D textile-reinforced cementitious composite specimens before and after exposure to elevated temperatures. Test results indicate that the 3D textile-reinforced cementitious composite lost its bearing capacity at 300 degrees C.
