Model of Time-Dependent and Stress-Dependent Chloride Penetration of Concrete under Sustained Axial Pressure in the Marine Environment

The effect of sustained compressive loading on the chloride penetration of concrete was investigated and a self-monitoring loading device was developed. A series of prisms were loaded under five different sustained axial stress levels and four different numbers of wet/dry chloride cycles. Both the apparent chloride diffusion coefficient Da and the surface chloride concentration Cs values were time and stress dependent with a sudden change threshold value of approximately 0.3 fc. A model was proposed to predict the chloride penetration profiles of concrete under sustained axial pressure, taking both the time-dependent and the stress-dependent characteristics of Da and Cs into account.
