* The bulk density is the mass of the material related to a specific volume and for cement is normally expressed as “kilograms per cubic metre”. * The bulk density reflects the volume taken up by the cement plus any air trapped between the p...
Density is simply a mass to volume ratio. Perhaps the easiest and most accurate way to calculate the concrete density is to measure some into a container of known volume and weighing it. One value of understanding, knowing, and monitoring the density of concrete is checking strength by using test cylinders.
The density of cement can be anywhere from 62 to 81 pounds per cubic foot, depending on the type of cement. General purpose cement, for example, can have a density up to 81 pounds per cubic foot.
Concrete has a very low coefficient of thermal expansion, and as it matures concrete shrinks. All concrete structures will crack to some extent, due to shrinkage and tension. Concrete which is subjected to long-duration forces is prone to creep. The density of concrete varies, but is around 2,400 kilograms per cubic metre (150 lb/cu ft).
Cement, mortar weighs 2.162 gram per cubic centimeter or 2 162 kilogram per cubic meter, i.e. density of cement, mortar is equal to 2 162 kg/m³. In Imperial or US customary measurement system, the density is equal to 135 pound per cubic foot [lb/ft³], or 1.25 ounce per cubic inch [oz/inch³] .
The density of normal concrete is about 145 pounds per cubic foot. The density of concrete is determined largely by the type of aggregate used in the mixture. The density of the cement used in the mix can also affect density, with compressed, vibrated cement creating a denser concrete mix.
As for concrete itself, the density of concrete of normal weight is about 2,400 kg per cubic meter, or 145 lbs. per cubic foot. The concrete density varies depending on the amount and density of the aggregate, how much air is entrapped or purposely entrained, the cement concentration, and the maximum size of aggregate used.

The density of cement plays a significant role both in its production and performance. The raw minerals are heated in huge ovens to promote chemical changes and this produces “clinker”. The final steps in cement manufacturing involve grinding (milling) and blending that produce the fine powder that is recognizable as cement.
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.
