Fresh Concrete Properties

Hardened Concrete Properties
Densities and Weights of Concrete made from different materials

Density in Place
Density of normal CLSM in place typically ranges from 90 to 125 pounds per cubic foot (1840 to 2320 kg/cubic m).
While conventional concrete has a density of about:
2300 kg/m3, lightweight concrete has a density between 160 and 1920 kg/m3.
Density 300-600 kg/m3 (19-38 lbs/ft3)
Made with Cement & Foam Only
Density 600-900 kg/m3 (38-56 lbs/ft3)
Made with Sand, Cement & Foam
Density 900-1200 kg/m3 (56-75 lbs/ft3)
Made with Sand, Cement & Foam
Density 1200-1600 kg/m3 (75-100 lbs/ft3)
Made with Sand, Cement & Foam
Typically, concrete has a density of <strong>150 pounds per cubic foot</strong> (150lbs/ft), which means that a block of concrete that is one foot wide, one foot long, and one foot high would weigh 150 pounds. Water has the density of only 62.4 pounds per cubic foot.
