Figure 2.11: The density as a function of compactability with respect to the number of
rammings 1-10. The first ramming starts from the left indicated by the number. The cross
placed in the middle shows the average value of the batches with an individual color. The
dotted lines are the standard deviations of compactability % as a horizontal line and the
standard deviations of density [ kg
m3 ] as a vertical line.
