Residual Properties of Fibre Grids Embedded in Cementitious Matrices after Exposure to Elevated Temperatures

چکیده
The use of fabrics in the form grids embedded cementitious matrices—usually termed as textile-reinforced mortar, fiber-reinforced matrix, or concrete—demonstrate a more stable performance elevated temperature conditions compared with polymers. This study investigated residual tensile properties bare yarns and mortar after exposure to 100 °C, 200 300 °C. Three different coated fabric textiles were used reinforcement: carbon, basalt, glass. Additionally, scanning electron microscopy (SEM), X-ray diffraction (XRD), thermos-gravimetric analysis (TGA) conducted evaluate potential changes internal structure fibers mortar. cracking stress, strength, ultimate strain composite specimens increased while only carbon glass fiber retained their effectiveness up At coupons reinforced basalt deteriorated rapidly. Only counterparts showed an improved overall due contraction differences coating material. results highlight three types important role material behavior.

Residual Tensile Strength and Bond Properties of GFRP Bars after Exposure to Elevated Temperatures
The use of fiber reinforced polymer (FRP) bars in reinforced concrete members enhances corrosion resistance when compared to traditional steel reinforcing bars. Although there is ample research available on the behavior of FRP bars and concrete members reinforced with FRP bars under elevated temperatures (due to fire), there is little published information available on their post-fire residual ...
