Q. What are the major factors affecting time of setting? A. The major factors affecting the time of setting are cement composition, water-cementitious material ratio (w/cm), temperature, and admixtures. When cement hydrates faster, the time of setting is reduced. Increases in the w/cm result in increased time of setting. Time of setting decreases as the temperature is increased. Admixtures may increase or decrease the time of setting depending on the type.
