The time of setting of hydraulic cement is primarily measured to ensure compliance with cement specifications ASTM C150, C595 and C1157. A modified Vicat needle (ASTM C807) is used to measure the time of setting of hydraulic cement mortar. This method is referenced in the specification for expansive cement ASTM C845.

Most California cement plants have a "reverse peak" electric load profile ( their demand is lower during the peak hours) because they consciously defer peak load. They try to stockpile certain crushed products when they can so that they can shut down or slow down large process mills or fans during the on peak hours.

Cement plant exposure can have a negative influence on the health of both employees and the general public. Gaseous matter and particulate matter are unrestrained into the surroundings during cement making and carriage (Raffetti et al. 2019).NOx, SOx, CO 2, CO, H 2 S, volatile organic carbons, dioxin, furans, and particulate matter are common emissions from cement manufacturing into the air.

In cement mills, ventilation is a critical key for maintaining temperature and material transportation. However, relationships between operational variables and ventilation factors for an industrial cement ball mill were not addressed until today. This investigation is going to fill this gap based on a newly developed concept named "conscious laboratory (CL)".
