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.

At a ready mixed concrete plant aggregates are typically stored in a bin or a stockpile. The process of taking a sample of aggregate that is truly representative of the nature and condition of the aggregate in the stockpile, bin or transfer point is called aggregate sampling. ASTM D75 is the standard practice for sampling aggregates.
