The cement density is used in the calculation of the total aggregate content and of the concrete density.Normal concrete has a density around 2400 kg/cubic meter or 4048 lb/cubic yard. There are many different kinds of concrete, many of which are much lighter. Cement is the liquid (or paste like) form, and tends to be much heavier than when it has cured into concrete.
"Cement" is not concrete, but can be used to make concrete by mixing with sand, stone and water. The density of cement is about 3120kg/m3.
To satisfy the ASTM standard requirements for normal consistency of cement: The Amount of Water that brings the cement paste to standard condition should vary between 22% to 30% by weight of dry cement.
It takes at least 10-25 minutes to be dry on the surface but at least an hour for it to be fully dry
it is 3 to 2
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.
Daft question really! Should be what is the density of cement. Does the question mean cement ( dry powder), wet concrete, set concrete or what?
what is cement density
The weight of dry cement typically ranges from about 94 to 100 pounds per cubic foot. This can vary slightly depending on the specific type of cement and its composition. For practical purposes, 94 pounds per cubic foot is commonly used in calculations for cement density.

how long does roof cement to dry
To calculate the density of cement, you need to know the mass of the cement and its volume. Divide the mass of the cement by its volume to get the density. The density of cement is typically around 1,440 kg/m³.

Contact cement is already dry on contact, and is very different from other adhesives because it needs to air-dry for 15 to 20 minutes before assembling. As for fast dry cement, special patching dry very fast depending on manufacturer some are as fast as 1 hour.
The bulk density of cement typically ranges from 1.1 to 1.4 grams per cubic centimeter, depending on the type and grade of cement used.
