Question

Difference between void ratio and porosity

Answer 1

Porosity is defined as a (volumetric)ratio of the volume of void-space (fluids and air together) ( ), and the total or bulk volume of material ( ), including the solid and voidcomponents (see Figure 1.1). ... Theporosity of loose soils can be about n=50%, while the porosity of compact soils is about n=30%.

Answer 2

Answer:

the voids ratio define how much voids present as compared to total solids in soil mass, where porosity say how much voids as compared to total volume of soil mass, in void ratio if the void increase in soil mass only top value change.
