Each test was repeated five times, and the calculated average of the
five tests was used as the value of the properties.
After each compaction test, the length, diameter and mass of each
briquetteweremeasured using amicrometer and an electronic balance,
respectively. Briquette density represents the ratio between the sample
mass and its volume, including pore volume. The volume of the briquettes
was calculated as the volume of a cylinder with the dimensions
(length and diameter) measured
