Figure 1. Typical strain versus time curve obtained from a linear compaction experiment on sodium chlorate. The compaction rate decreases with time as a consequence of densification of the aggregate.

Figure 2. Typical logarithmic strain rate versus logarithmic strain curve obtained from the same linear compaction experiment on sodium chlorate as in figure. 1. The compaction rate decreases with the strain approximately following a power law with an exponent of about -2.

Figure 3. Effect of compaction rate on grain size displayed in logarithmic strain rate versus logarithmic strain graphs of three experiments on sodium chlorate with different grain sizes, but at otherwise similar conditions. As a first approximation, at a strain of 0.1, the strain rate depends on the grain size to the power -3.
