## Specific Gravity of Concrete PDF Density Materials

The weight of a batch of concrete varies with its composition, but a typical concrete mix about 145 pounds per cubic foot (pcf). Specific gravity is the ratio of the weight of a cubic foot of a material to the weight of a cubic foot of water, which is 62.4 pcf. Therefore, the specific gravity of a typical concrete mix is 145/62.4 or 2.32.
