1. Measure the dry mass of total specimen, Ms.
2. Determine the solid volume from the known specific gravity as:
s
s
s w
M V =
G ρ
3. Determine equivalent height of solids as:
H = V A s s
where: A = specimen area
4. Initial void ratio is obtained as:
0 s
0
s
H -H
e =
H
where: H0 = initial height of specimen
5. Current void ratio is obtained as:
s
s
H-H
e=
H
where: H = current height of specimen
