Dry cement in bags is stored in a dry place protected from the weather. For large construction sites this is usually a secure storage area. If you are talking about mixed cement (wet) or concrete, then it is not stored on a construction site. It is mixed off-site and carried to the site in large "cement mixer" trucks. The it is placed (or poured) prior to the initial setting time specified by the concrete manufacturer.
If your asking who does the mix design for cement or concrete that would normally be done by civil/construction engineers. The chemical engineers may play a roll if they are creating a new additive to make the cement or concrete dry faster while retaining or improving its design strength.
