Abstract: 
In this study the accelerated chloride migration test is applied to estimate the chloride migration rate of mortar. In order to investigate the effect of aggregate content on the chloride migration rate of mortar, specimens with different fine aggregate volume fractions were cast and tested. The chloride migration rate of mortar is used to assess the dilution, tortuosity, and interfacial transition zone (ITZ) effects of aggregate in the cement-based composites. A model modified from the Bruggeman theory for the migration rate of mortar is used, and the regression analysis is used to determine the approximate chloride migration rate of ITZ.
