Water Absorption Properties of Cement Pastes: Experimental and Modelling Inspections

Table 3

IFU input data to models C-1, C-2, C-3, and C-4. The fractal dimension (D_f), the maximum (R_max) and minimum rays (R_min), the number of iterations, the number of solid forever squares for each base unit (the Sierpinski carpet), the number of B base units (n_B), the filled surface (FS) used to build the IFU, and comparison between experimental (ε_exp) and predicted pore volume fractions (ε_IFU).
