“…Wang et al [9] observed that compressive fatigue load had a significant effect on residual strain, and the concrete was subjected to compressive fatigue damage through residual strain in three stages; concrete damage accumulated more rapidly as the residual strain increased. Nakhi et al [14], Gontar et al [15], and Tran et al [16] concluded that the Cl − permeability of concrete after fatigue load also mainly depends on the residual strain of concrete, which gradually increases as the residual strain increases. The stress level required, when the Cl − permeability of concrete started to increase significantly after unloading by multiple fatigue loads, was lower than that of concrete after unloading by one load, which is consistent with the gradual accumulation of internal damage in concrete under fatigue load.…”

The service environment of concrete in the marine environment is harsh, and demands regarding the durability of marine concrete have increased. Marine concrete in harbor and wharf areas suffers from the combined effect of fatigue load, dry–wet cycles, and Cl− erosion, which can result in spalling of the concrete surface, corrosion of the internal reinforcement, and even concrete damage. This paper reviews recent research results on the durability of concrete and reinforced concrete (RC) under the combined effect of fatigue load, dry–wet cycles, and Cl− erosion. We further assess the variation in Cl− transport properties with fatigue load, the causes behind the reduction in the carrying capacity of RC products under fatigue load, the methods of Cl− erosion on concrete under the pressures imposed by dry–wet cycles, and the damage of the protective layer of concrete due to accelerated Cl− erosion caused by the action of dry–wet cycles. Further studies are needed on the durability of concrete under the action of fatigue load, wet and dry cycles, and Cl− erosion, in addition to the testing of the durability of concrete under the combined effects of the afore-mentioned various factors.
