“…Gerard et al (1998) and Xiang and Zhao (2007) respectively introduced a damage parameter to modify the chloride diffusivity and established a chloride diffusion model for stressed concrete. Ožbolt et al (2010) modeled the damage and cracking phenomena using smeared cracks method, and analyzed the effect of damage on the mass transport properties of concrete. In addition, many researchers (e.g.…”

In this paper, a comprehensive investigation regarding the loading effects on chloride diffusion in saturated concrete is reported. It involves both theoretical and experimental aspects, towards contributing to the service-life prediction of infrastructure under chloride attack. A revised chloride diffusion model is proposed based on the modified Fick's second law with an emphasis on the loading effects. In particular, this influence is quantified using a newly-introduced damage effect factor defined by tortuosity and constrictivity of damaged concrete. This model is capable of predicting the chloride profiles in concrete under different loading states, regardless of whether it is damaged or undamaged. Meanwhile, a series of experimental studies were extensively operated in order to analyze the influence of loading on chloride diffusion process. Two types of mixtures (i.e. ordinary concrete and ordinary concrete mixed with slag) were investigated for chloride diffusion tests under different natures (i.e. compressive and tensile loads) and magnitudes of loads. Totally four levels of loads were applied to further correlate the relation between chloride diffusivities and associated strain values. Finally, two groups of test data with different tensile strain were adopted to validate the theoretical model. It shows that the model is reasonable and the numerical result is adequately accurate.

“…Ožbolt, Balabanić, Periškić, and Kušter (2010) developed a 3D numerical model for transport of capillary water, oxygen and chloride through the concrete taking into account the interaction between the non-mechanical processes and mechanical properties of concrete in order to investigate the influence of damage of concrete on depassivation time of reinforcement, the influence of concrete quality, cracking and water saturation in concrete on the current density (Ožbolt, Balabanic, & Kušter, 2011), the transient analysis of corrosion processes before and after depassivation and the corrosion-induced damage of steel reinforcement (Ožbolt, Oršanić, & Balabanić, 2014;Wang & Ueda, 2011) quantified the chloride diffusion coefficient of concrete by means of a meso-scale modelling method based on available experimental results from literature. Park, Kwon, and Jung (2012) proposed an analytical model for the evaluation of chloride behaviour in cracked concrete considering both chloride diffusion and water permeation in a Representative Element Volume.…”

The presence of cracks in reinforced concrete structures added to the chloride-induced steel corrosion is worldwide one of the major causes of deterioration of reinforced concrete structures, producing loss of structural strength and stability. This study deals with the influence of artificial cracks on chloride penetration in mortar specimens by presenting both the experimental and the numerical results. The experimental results were obtained using chloride penetration tests on mortar specimens of different sizes, with and without artificial cracks, subjected to chloride exposure. Numerical results were obtained using transient finite element analysis by simulating chloride mass diffusion. Comparisons between the results on chloride penetration concluded that the numerical ones obtained using the mass transfer modulus agrees fairly well with the experimental ones. In addition, the influence of certain crack parameters such as crack length, crack depth and also time exposure on chloride ingress was considered.
