Porosity and Particle Size | Science Project

Porosity refers to the ratio of the volume the air spaces take up in the rock to the total volume of the rock. In general, larger particles cannot pack together as well as smaller particles can, which means that packing larger particles together leaves more room for air and gas to fill in between the particles, making the rock more porous.

Crushed Rock in Arlington, WA | East Valley Sand and Gravel

Like gravel, crushed rock has a variety of uses, but most are underground. Smaller crushed rock – between ½inch and ¾inch – is used as a base for concrete pours, as backfill, for drainage systems or as pipe bedding.

How to Calculate the Volume of Voids | Sciencing

Sep 25, 2019· The void ratio (e) is the ratio of the volume of voids (V v) to the volume of solids (V s). Porosity (n), on the other hand, is the ratio of the volume of voids (V v) to the total volume (V) or volume of the voids plus the volume of the solids (V v +V s).
