3. 1 Calculate the apparent density of the material before and after application of the load as follows, making separate calculations for both H1, and H2:
V = H × A
Apparent density = W/V
where:
V = volume occupied by the material in the measuring cylinder, cm³,
H = height of the material in the measuring cylinder, cm,
A = cross-sectional area of the measuring cylinder (60 g).
3.2 Make three determinations of the apparent density on each sample and average these results separately.
