Due to their high strength, corrosion resistance, and durability, fiber reinforced polymers (FRP) are very attractive for civil engineering applications.
One of these applications is the strengthening of concrete columns with FRP sheets.
The performance of this strengthening technique at elevated temperature is still questionable and needs more investigations.
This research investigates the effects of exposure to high temperatures on the compressive strength of concrete cylinders wrapped with glass and carbon FRP sheets.
Test specimens consisted of 30 unwrapped and 60 wrapped concrete cylinders.
All specimens were exposed to temperatures of 100, 200, and 300°C for periods of 1, 2, and 3 hours.
The compressive strengths of the unwrapped concrete cylinders were compared with their counterparts of the wrapped cylinders.
For the unwrapped cylinders, test results showed that the elevated temperatures considered in this study had almost no effect on their compressive strength; however, the wrapped specimens were significantly affected, especially those wrapped with GFRP sheets.
The compressive strength of the wrapped specimens decreased as the exposure period and the temperature level increased.
After three hours of exposure to 300°C, a maximum compressive strength loss of about 25.3% and 37.9%, respectively, was recorded in the wrapped CFRP and GFRP specimens.
