Sieve Analysis
Gradation from Sieve Analysis . The gradation is as follows. Well graded: All particle sizes are included. Uniformly graded: Most of the particles are of same size. Gap graded: Some of the particle sizes are missing. For the soils passing through 75 micron sedimentation analysis would be done, deflocculating agents are used to deflocculate the soil retained on 75 micron, then …
Crushing strength of artificial single-particle considering
The 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.
Evaluation of the crushing characteristics of industrial waste
Shifting 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].

A Manual for Design of Hot-Mix Asphalt with Commentary
The densest possible aggregate gradation, called the maximum density gradation (or sometimes the Fuller maximum density curve), can be approximately calculated using the following formula: where % PMD = % passing, maximum density gradation d = sieve size in question, mm D = maximum sieve size, mm Figure 4-4 illustrates the different types of ...
Gradation equation of coarse-grained soil and its applicability …
Gradation equation is one way to describe the gradation of coarse-grained soil conveniently, exactly and quantitatively. With the gradation equation, the influence of gradation on the mechanical behaviors of coarse-grained soil can be expressed quantitatively. A new gradation equation with a parameter is proposed. The basic properties and applicability of the …

Furthermore, an S-shaped curve is preferable for the gradation curves [23,25]. Thus, the family of gradation curves were designed by adjusting the passing rate of BSS in S-shaped curves. Seven gradation curves were numbered gradations 1–7 according to the passing rate of BSS, from the largest to the smallest, as shown in Table 6 and Figure 2.
Study on the influence of microcracks of coarse aggregate
The loading speed of the virtual crushing test is set to 0.01 m/s. The influence of microcracks on the Weibull distribution of crushing strength is considered from three aspects: quantity, location and direction. The characteristic strength of Weibull distribution of basalt particles is positively correlated with the number of microcracks.

2.7.1 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.
