Assessment and Prediction Model of GFRP Bars’ Durability Performance in Seawater Environment

Buildings, 2022
In this study, the performance degradation law and mechanism of glass fiber reinforced polymer (GFRP) bars were investigated by being immersed in natural seawater (denoted as SW), saline-alkali solution (SA), or wrapped with concrete, and then submerged ...

BOND BEHAVIOR OF GFRP BARS IN CONCRETE WITH CARBON NANOTUBES

, 2023
This work investigates the adherence of 12.7 mm glass fiber-reinforced polymer (GFRP) bars in concrete with carbon nanotubes (CNT) through pull-out tests. Eighteen specimens were used to investigate the impact of CNT content (0% and 0.05% by weight of cement) and anchorage length (5d and 10d).
