In this research, the particle size distribution and permeability of saturated crushed sandstone under variable axial stresses 0, 2, 4, 8, 12, and 16 mpa were studied.X-ray computed tomography results revealed that particle crushing is likely to occur considerably as the axial stress is approaching 4 mpa, which results in the change of pore structure greatly.

The pore size distribution, in turn, is controlled by mineralogy, maturity, kerogen type and mineralogy.For example, the mineralogy affects the moisture content with clay-rich shale sorbing more.
The distribution coefficient k d of radionuclides on bedrock is one of the key parameters used in the safety analysis of spent nuclear fuel repositories.Typically, distribution coefficients have been determined using crushed rock.However, recent studies have shown that crushing of the rock increases considerably the distribution coefficient compared with the values of intact rock.
The size distribution is often of critical importance to the way the material performs in use.A sieve analysis can be performed on any type of non-organic or organic granular materials including sands, crushed rock, clays, granite, feldspars, coal, soil, a wide range of manufactured powders, grain and seeds, down to a minimum size depending on.

The intersection of discontinuities or fractures within a jointed rock mass may result in the presence of individual blocks of intact rock within the surrounding rock matrix.The range of sizes of such blocks is represented as the in-situ block size distribution ibsd.
Gravel sizes can vary a little bit by location and distributor, but in most cases the crushed rock composite is available in more or less uniform sizes ranging anywhere from fine powder to pea-sized, coin-sized, or even golf ball-sized pieces.Most retailers and outlets used a numerical system to assign a size.
