Abstract

This paper presents the results of an experimental investigation into carbon fiber reinforced polymer (CFRP) exposed to simulated environments of different types of seawater sea sand concrete (SWSSC) for 3 months under an accelerating condition. Scanning electron microscopy (SEM) revealed interface debonding and matrix degradation in the case of all simulated concrete solutions at 60 °C. However, continuous cracks were found along the interface exclusively in the case of seawater sea sand normal concrete (SWSSNC) and normal concrete (NC) solutions. Such cracks are quite likely to facilitate the penetration of solution into the bulk. The CFRP specimens suffered less weight gain in SWSSC solutions (i.e. SWSSNC, SWSSHPC) than in conventional concrete solutions (i.e. NC, HPC).
