WitrynaNatural geomaterials often exhibit pore size distributions with two dominant porosity scales. Examples include fractured rocks where the dominant porosities are those of the fractures and rock matrix Witryna14 kwi 2024 · To further analyze the pore size distribution in the shotcrete, four diameter thresholds (0.5 mm, 1 mm, 2 mm and 3 mm) were selected to divide the pores into five different groups, as depicted in Fig. 6. For both NSC and FSC, pores with a diameter smaller than 0.5 mm accounted for more than 50%, and the total proportion of pores …
