Computational investigation on mass diffusivity in Portland cement paste based on X-ray computed microtomography (μCT) image (2012, background): “[11] where the degree of pore connectivity derived from the microtomography images of cement paste (w/c = 0.”
Effects of water content, magnesia-to-phosphate molar ratio and age on pore structure, strength and permeability of magnesium potassium phosphate cement paste (2014, background): “Since the formation factor can be related to the porosity as [48]”
X-ray microtomography shows pore structure and tortuosity in alkali-activated binders (2012, methodology): “This is because the segmented porosities of OPC binders obtained by the transition point method were close to the percolation limit, while the theoretical segmented porosities were well above the percolation limit [14], and are more comparable to those obtained in this study.”
