Preventing Plastic-Shrinkage Cracks in GFRP-Bar Reinforced Concrete Using Fibers

International Journal of Concrete Structures and Materials
Large horizontal concrete elements are susceptible to premature cracking due to environmental effects. The ASTM C1579 bottom-restraining technique cannot reliably induce controlled cracking.

Properties of GFRP Bars Subjected to High Temperature

Engineering, Technology & Applied Science Research
This study evaluates the properties of Glass Fiber Reinforced Polymer (GFRP) bars exposed to high temperatures. An experimental program was carried out, which investigated 30 samples burned at different temperatures, 300 °C, 500 °C, and 700 °C, and compared them with additional unburned samples.

Repairing and Strengthening of Box-Section RC Beams Reinforced by GFRP Bars Using Epoxy Injection and GFRP Strips

International Journal of Concrete Structures and Materials
Glass-fiber-reinforced polymer (GFRP) bars are widely applied due to their advantages over reinforcement steel bars. GFRP bars are the main adhesive reinforcement since they have a high strength capacity and corrosion resistance.
