“…(hollow square in scatter plot) match well with the curve for the predicted permeability according to the attenuation when the tortuosity was 10 (green curve). In impermeable concrete materials, the value of tortuosity is in the range of 10-25 when the porosity is in the range of 6-10% [29]. The difference between the measured and predicted permeabilities was calculated to be under 2.58×10 -9 m/s with 1.42×10 -9 m/s of standard deviation.…”

“…However, different factors such as the geometry and the heterogeneity of the cementitious materials, the presence of steel reinforcement and moisture, make these methods less precise. Boukhatem et al [19] used a soft computing approach to predict the transport tortuosity of the pore system of fly ash concrete by building an intelligent hybrid system. In their system, a genetic algorithm was used to optimize the structure and the hyper-parameters of the network.…”
