The maximum particle size of the aggregate used in this test was 10 mm, as recommended by the ASTM and some other studies on the particle size effect [64,71]. The waste rock should be crushed and sieved into 0–0.5 mm, 0.5–1.0 mm, 1.0–1.5 mm, 1.5–2.5 mm, 2.5–5.0 mm, 5.0–8.0 mm, and 8.0–10.0 mm particles.

The particle size is larger than the boundary size are coarse collected materials, and the rest are fine collected materials. In civil engineering, particle size > 4.75 mm are coarse aggregates, it can also called “ stone “; The aggregates with particle sizes > 0.15mm and < 4.75 mm are fine aggregates, also known as “ sand “.

This indicates that greater quantities of rock dust are needed to inert as the average rock dust particle size increases. Rock dust with an average SSA of 446 m 2 /kg (Z = 1.9) required about 65% rock dust to inert the PPC, while rock dust with an average SSA of ~49 m 2 /kg required about 90% (Z = 9.0) to inert the PPC.

The particle size of the SJK granite was between 0.45 and 4.00 mm and is mainly concentrated at 3.00 mm. The particle sizes of these three kinds of rock were distributed in three orders of magnitude, so the influence of the surrounding rock particle size on the spalling slice morphology can be well observed.

To generate particle size distribution curves, a set of sieves were selected based on ASTM standards (American Society for Testing and Materials. Committee D18 on Soil and Rock 2004). Table 2 shows the sieve sizes chosen for the study. Equivalent diameters of all the particles are divided into intervals based on the ASTM sieve sizes, and the

Crushing of rock particles is a phenomenon commonly encountered in geotechnical engineering practice. It is however difficult to study the crushing of rock particles using classical theory because the physical structure of the particles is complex and irregular. This paper aims at evaluating fractal and morphological characteristics of single rock particle. A large number of particle crushing

Particle size distribution curves of marble to marble/hornfels waste rock reveal these materials are both coarse grained (davg = 23 ± 10 mm) and favor preferential flow regimes. Conversely, intrusive material (found in Pile 5) is significantly finer grained (davg = 1.9 ± 2.7 mm) and favours slower, matrix flow regimes.

Particle size is an important textural parameter of clastic rocks because it supplies information on the conditions of transportation, sorting, and deposition of the sediment and provides some clues to the history of events that occurred at the depositional site prior to final induration.
