Sand particle crushing generates coarse fragments with size d ⩾ 75 μ m and fine fragments, i.e., "fines," with size d < 75 μ m.Yet, postcrushing fines are seldom characterized due to testing constraints. An experimental study was conducted to examine the size distribution evolution of fine fragments generated by crushing two uniform sands with contrasting degrees …
