In addition, the basalt single particle crushing test is designed and implemented to obtain typical load-displacement curves, enabling a comprehensive analysis of the data characteristics associated with the crushing points, and serving as a basis for validating the calculation results of the FDEM model. 2.1. Morphology acquisition
اقرأ المزيدThe relationship between the microcracks of a single particle and the crushing strength was studied by virtual experiments. The three-dimensional profile of a single particle was obtained by CT-scanning technology. The particle bonding model is used to fill the three-dimensional contour to construct virtual particles, and the virtual …
اقرأ المزيدAs the input work increases, the grading curves of coarse-grained soils shift leftward, and the relative crushing increases. Among the three representative particle morphological parameters (i.e., aspect ratio, convexity and sphericity), the particle sphericity most significantly influences the deformation and crushing properties of coarse ...

اقرأ المزيدIn this curve, the cumulative percentage of material passing down is plotted inordinate, and the size of the sieve opening is plotted in abscissa which is a logarithmic scale. Types of aggregates on basis of gradation curve 1) Uniformly graded Aggregates. This refers to the sample which consists of a particular size of aggregates predominately.
اقرأ المزيدShifting in the gradation curve is basically caused by the formation of smaller particles during grain crushing. As a result, a material changes its state from a poorly graded to a well-graded state as evident from various other studies where a significant change in the gradation curve before and after crushing is observed [25], [57].
اقرأ المزيدDeveloping a Gradation Curve with Physical Soil Sample Data. In this option, gradation curves are developed based on the availability or collection of data from physical soil sampling. For subbasin elements, it should be noted that these gradation curves do not affect the computation of the bulk sediment discharge.

اقرأ المزيدIn order to verify the rationality of determining the aggregate gradation curve for pavement base or subbase by fractal calculation, the particle content in the corresponding range is sequentially calculated and the gradation curve is drawn according to formula, with the fractal dimension D value determined in Table 2.
اقرأ المزيدThe gradation curve of the spherical particle is on the far right except for the original gradation curve. This phenomenon can be explained by the fact that the single-particle crushing test is terminated when the spherical particle is broken into three or four parts, so the ranges of the gradation are relatively narrow.
اقرأ المزيد2.7.1 Gradation Curves. A typical gradation curve shows the passing percentage of aggregates at different sieve sizes. In a gradation curve chart, the horizontal axis is the sieve size usually in a logarithm scale or 0.45 power scale. The log or 0.45 power transform can spread out the small values and bring large values closer together.
