The floe size, internal pore size, mass fractal dimensions determined from free-settling test or small angle light scattering test, aeral porosity, boundary fractal dimension and Sierpinski carpet fractal dimension of pore boundary from 2D slices, and the volume porosity, compactness, and the pores' box-counting fractal dimension from three-dimensional reconstructed image, were estimated and compared.Floc structureFlocculationFreezingImage analysisconference paper2-s2.0-7744243928https://www.scopus.com/inward/record.uri?eid=2-s2.0-7744243928&partnerID=40&md5=b39e14c69bd3bd63f3c74e25c5903878
