Micro–macro properties of quartz sand: Experimental

2015-1-1  The experimental results show that the D50 value of quartz sand is 600 μm. Therefore, in DEM simulations the following PSD can be used to determine the effect of sand granulometry on the macroscopic properties of quartz sand. Table 1 shows the PSD of quartz sand that is going to use in DEM simulation.
