May 29, 2010· Cement The majority of precast concrete plants today employ bulk cement in their operations. Bulk cement is stored in circular or square silos made of concrete or steel. Given that cement is sensitive to moisture and must remain dry until used, the silos must be watertight. If kept dry, cement will retain its quality for a very long time.
