The crushing strength and crushing energy of large particle size are then analyzed by numerical models. The results show that the fractal dimensions of different materials are different under the same test conditions. The fragmentation degree of sandstone with different grain sizes is greater than that of mudstone.

Procedure The aggregate sample: The material for the standard test consists of aggregates sized 10.0 mm to 12.5 mm.The aggregates must be in a surface dry condition before testing. The aggregates may be dried by heating at 100 oC – 110 o C for not more than 4 hours and cooled to room temperature before testing, if necessary.

Shergold and Hosking (1959) showed for a number of materials including two rock types that the fines versus load relation in the aggregate crushing test gave a non-linear relation. They also suggested that there was a linear relation between 7.5 to 12.5% fines range, passing through the coordinates (0.–4) in the fines versus load diagram ...
