##tihuan2##Fig. 7 illustrates a schematic model of the particle crush value test both in the laboratory and in the DEM simulation. The loading rate for the laboratory particle crush value test was set at 0.5 kN/s. Upon reaching an axial load level of either 300 kN or 400 kN, the current axial load was maintained for approximately 5 seconds.
