Abstract
Using sensor-based electrical data, empirical time-dependent tortuosity (Ï) formulas as functions of pore size distribution (PSD) parameters were developed for 12 hydrating mortar mixtures. The inverse of the formation factor (FF) was used to obtain Archie's exponent (m), which is an indicator of tortuosity. PSD parameters were inferred from theoretical water vapor sorption isotherms. The results clarify the effects of curing time and mixture design on FF and tortuosity. Additionally, it is shown that m correlates with pore system refinement and increase in disparity of pore sizes, suggesting the usefulness of this parameter in describing pore system's intricacy.
