Concrete is a kind of artificial stone that is formed by mixing a binder material (cement or lime) with aggregates (fine & coarse aggregate), water, admixtures, etc. in specific mix ratio. Mix ratio is the key factor for Strength and quality

Density is important to factor for concrete so, Before going to know the density of concrete know,

Why is the density of concrete important?

The mechanical properties of concrete are greatly affected by its density. Dense concrete generally offers greater strength and less voids and porosity. The voids in the concrete is small, which makes it less susceptible to water and soluble elements.

Constant Values Of Concrete Density

We have found the following sources which give a constant value for the density of concrete.

 In Dorf, Richard. Engineering Handbook. New York: CRC Press, 1996.

The normal concrete density is 2400 kg/m3 (2.4 g/cm3 - 150 pcf or lb/ft3)

The lightweight concrete density is 1750 kg/m3 (1.75 g/cm3 - 110 pcf or lb/ft3)


In Brooklyn Public Library Files; 1999

Typical density of concrete 2.3 g/cm3 (143.6 pcf or lb/ft3 - 2300 kg/m3)


In McGraw-Hill Encyclopedia of Science and Technology.

Volume generally assumed for the density of hardened concrete is 150 lb/ft3 (2400 kg/m3 - 2.4 g/cm3)


In Concrete Basics. Portland Cement Association.

On-site density: The density of normal on-site CLSM generally varies from 90 to 125 pounds per cubic foot (1840 to 2320 kg/ m3 or 1.84 to 2.32 g/cm3)


In Conversion Factors, Material Properties and Constants, Edward Boyden, MIT.

Density Concrete 2242 kg/m^3


Material Notes. Faculty of the Built Environment, University of New South Wales.

Conventional concrete has a density of about 2300 kg/m3 or 2.3 g/cm3

Light weight concrete has a density between 160 and 1920 kg/m3 (0.16 to 1.92 g/cm3).


Cube Competition. Concrete Society of Southern Africa.

The concrete must be of a lightweight nature, with a mass of not greater than 1.5 kg/100 mm cube or a density of 1500 kg/m3


Baldwin, Kelly. Electrically Conductive Concrete: Properties and Potential. Construction Canada. Vol. 98, No. 1 (January/February 1998): 28-29.

Density of concrete 1450–1850 (kg/m3) or 1.45 to 1.85 (g/cm3).


Is any one buried in Hoover Dam? Bureau of Reclamation, US Department of the Interior.

Typically, concrete has a density of 150 pounds per cubic foot, ie. a block of concrete that is one foot wide, one foot long and one foot high weighs 150 pounds. The water density is only 62.4 pounds per cubic foot.
