void volume crushing

What is activated carbon?

 · Mesodensity or bulk density: It should be the volume of activated carbon per unit volume of pore volume and interparticle void volume. Bulk density and particle density: The weight per unit volume of activated carbon should be the pore volume and not the inter-particle void volume. Strength: the crush resistance of activated carbon.

Void ratio

The void ratio of a mixture is the ratio of the volume of voids to volume of solids.. It is a dimensionless quantity in materials science, and is closely related to porosity as follows: = = = and = = + = + where is void ratio, is porosity, V V is the volume of void-space (such as fluids), V S is the volume of solids, and V T is the total or bulk volume. This figure is relevant in composites ...
