Unlike industrial mills, laboratory grinding mills operated over given time interval do not account for CL, therefore leading to different cement particle size distribution (PSD) curves [11, 12]. This consequently alters cement properties such as water demand, rheology, and hydration processes such as heat release, setting time, volume change, and strength development [ 13 , 14 ].
