Abstract

This paper presents experimental and theoretical methods to study the damage layer evolution of a breakwater made with concrete hollow squares in marine environment. Wetting time was directly related to the performance degradation of the breakwater by observation. The thickness of damage layer was detected by means of ultrasonic testing. Meanwhile, some samples drilled from concrete hollow squares were analyzed by SEM and XRD in order to illustrate the damage mechanism. Subsequently, a theoretical model containing wetting time ratio was established to simulate the damage layer evolution based on Fick’s second law, which could be suggested to predict the service life of concrete structures in marine environment.
