Permeability is a measure of a rock’s:
Web15%. Rock porosity is often less than 2%. Porosity is a crude but sometimes useful measure of the quality of concrete. Very porous concrete will generally be both weak and permeable to liquids and gasses. Permeability is a material property that indicates the ease with which any liquid or gas flows through the con-nected pores in a solid. WebApr 12, 2024 · The tests in the 2nd and 3rd campaigns, where pore pressure was taken into account, imposed special requirements on the specimen preparation. It was necessary to refrain from a complete re-profiling of the end surfaces using acrylic resin, because the latter would seal the rock, making the measurement or control of pore pressure impossible.
