Crushed Stone - The Unsung Mineral Hero

Sandstone is generally composed of sand grains cemented together by calcite, clay, or silicate minerals that have precipitated between the sand grains The cement usually does not completely fill all of the voids between the sand grains, leaving a porosity that typically ranges between 5 and 30% This pore space allows the rock to absorb water

Porosity - Wikipedia

Porosity - Wikipedia

Porosity or void fraction is a measure of the void (ie "empty") spaces in a material, and is a fraction of the volume of voids over the total volume, between 0 and 1, or as a percentage between 0% and Strictly speaking, some tests measure the "accessible void", the total amount of void space accessible from the surface (cf closed-cell foam)
