Flexural behaviour of reinforced concrete beams strengthened with a composite reinforcement layer: BFRP grid and ECC (2016, background): “However, the bonding behaviour at the FRP-to-concrete interface may deteriorate due to environmental factors, such as moisture, high temperature and fire [8, 9] because of the organic property of the epoxy material.”
Fire behaviour of reinforced concrete beams strengthened with CFRP laminates: Protection systems with insulation of the anchorage zones (2012, background): “[11,12] on CFRP-strengthened concrete members showed a rapid loss of strength when epoxy adhesive temperature increased beyond 60–70 C.”
An overview on the potential of geopolymers for concrete infrastructure rehabilitation (2012, background): “According to Gamage et al [45] both experimental results and finite elements calculations show that epoxy adhesives should not be exposed at temperatures above 70 C, in order to maintain the integrity of the strengthened elements.”
Bond-Slip Model for FRP Laminates Externally Bonded to Concrete at Elevated Temperature (2013, background): “However, existing studies (e.g. Gamage et al. 2006; Gao et al. 2010) have shown that this approach is usually impractical because the fire protection layer needed can be excessively thick (e.g. 70mm for achieving a two-hour fire resistance rating for the epoxy).”
