the porosity decreases until a limit is reached that represents random frictionless packing, which occurs at 0.399 porosity, and is independent of grain size. No further loss of porosity is possible for randomly packed spheres, unless the grains undergo irreversible deformation due to …

Porosity reduction from that of the original block (left) by the reduction of the number of the pipes (middle), the radius of a pipe (third to the right), and radius of the kernels. Consider a solid block with a square cross-section with a 10-3 m side and the

Watch for washed out hole (high Caliper) and bad density data 4.7 Note: Both φ N and φ D should be calculated with respect to limestone. φ N is recorded on limestone matrix and φ D ...
