Bond mechanism and bond strength of GFRP bars to concrete: A review (2016, methodology): “By use of this thermal feature in GFRP bar, high temperature is often implemented as accelerated testing to predict long-term (75to 100-year) durability of FRP bar reinforced concrete [26,27,32,105].”
Long-term durability prediction models for GFRP bars in concrete environment (2012, background): “Second, according to the assumed relationship of Equation (4), the strength approaches infinity at time zero.”
Effect of aging on bond of GFRP bars embedded in concrete (2010, background): “Moreover, FRP bars—especially GFRP bars—are susceptible to attack under exposure to moisture, alkaline solutions, and elevated temperature [9,10].”
Laboratory assessment and durability performance of vinyl-ester, polyester, and epoxy glass-FRP bars for concrete structures (2017, background): “The three dominant deterioration mechanisms include matrix osmotic cracking, interfacial debonding, and delamination (Chen et al., 2007).”
