Drop shatter test was conducted according to ASTM D-440-86 [39]. Initial mass (a) of the briquette was weighed, then the sample was placed into the testing machine and dropped from 1.8 m above a steel plate. The dropped briquette was returned to the machine and the process was repeated one more time. Dropped briquette and its crumbled parts were sieved. Mass of briquette remaining in the sieve counted as the final mass of briquette (b). DSI was calculated using Equation (7).
