Find how much concrete weighs by beginning the volume below. Use our concrete calculator to discover the volume that concrete.

You are watching: Weight of a cubic yard of concrete

A typical concrete mix weighs 150 lbs per cubic foot, 4,050 lbs per cubic yard, or 2,400 kg per cubic meter. The load of concrete is figured out by its density, which can vary based upon the quantity of aggregate, water, and also air in the mix.


Determine the thickness of Concrete

Density is the measure up of mass for a given volume and also is identified by the formula:

density (p) = massive (m) ÷ volume (V)

The density of concrete is 3.15 g/cm3 if the density of accumulation will differ by the kind of rock used. For instance, gravel has actually a much greater density than vermiculite. The thickness of a typical concrete mix is 2.4 g/cm3 or 150 lbs/ft3.

Different mixes of concrete will use much more or less aggregate as well. Because that instance, the desired concrete mix because that a countertop will have less accumulation than the mix because that a driveway, i m sorry will affect the density and also thus the weight of the concrete.

Determine the weight of Concrete

The thickness of concrete is figured out by mass and also volume, since density is understand the formula because that mass can be readjusted by multiplying the thickness by the volume.

mass (m) = volume (V) × density (p)

Example: discover the weight of 25 cubic feet of concrete

weight = volume × densityweight = 25 × 150weight = 3,750 lbs

Example: find the load of 3.5 cubic yards of concrete

weight = 3.5 × 4,050weight = 14,175 lbs
