Find exactly how much concrete weighs by entering the volume below. Usage our concrete calculator to uncover the volume that concrete.

You are watching: How many pounds in a cubic yard of concrete

A typical concrete mix weighs 150 lbs per cubic foot, 4,050 lbs every cubic yard, or 2,400 kg every cubic meter. The load of concrete is determined by that density, which deserve to vary based upon the lot of aggregate, water, and air in the mix. ### Determine the density of Concrete

Density is the measure of mass because that a offered volume and also is characterized by the formula:

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

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

Different mixes of concrete will use more or less aggregate as well. For instance, the wanted concrete mix for a countertop will have actually less aggregate than the mix because that a driveway, i m sorry will impact 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, due to the fact that density is know the formula because that mass have the right to be adjusted by multiplying the thickness by the volume.

mass (m) = volume (V) × thickness (p)

Example: discover the weight of 25 cubic feet that concrete

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

Example: uncover the weight of 3.5 cubic yards that concrete

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