Durability of fiber reinforced polymers (FRPs) in seawater sea sand concrete (SWSSC)

Fiber reinforced polymers (FRP) are promising alternatives to carbon steel rebars as strengthening materials for seawater sea sand concrete (SWSSC) to mitigate the critical problem of unacceptable corrosion rate of steels in this high chloride-containing concrete environment. This thesis presents two experimental investigations on durability of three different types of FRPs in simulated SWSSC environments to enable more accurate service life prediction and suitable strengthening material selection for SWSSC, which is of great significance for civil infrastructures with a typical service life of 50-100 years.
