## How Much Does Concrete Weigh

A typical concrete mix weighs 150 lbs per cubic foot, 4,050 lbs per cubic yard, or 2,400 kg per cubic meter. The weight of concrete is determined by its density, which can vary based on the amount of aggregate, water, and air in the mix.

### Determine the Density of Concrete

Density is the measure of mass for a given volume and is defined by the formula:

density (p) = mass (m) ÷ volume (V)

The density of concrete is 3.15 g/cm^{3} while the density of aggregate will vary by the type of stone used. For instance, gravel has a much higher density than vermiculite. The density of a typical concrete mix is 2.4 g/cm^{3} or 150 lbs/ft^{3}.

Different mixes of concrete will use more or less aggregate as well. For instance, the preferred concrete mix for a countertop will have less aggregate than the mix for a driveway, which will affect the density and thus the weight of the concrete.

### Determine the Weight of Concrete

The density of concrete is determined by mass and volume, since density is know the formula for mass can be changed by multiplying the density by the volume.

mass (m) = volume (V) × density (p)

**Example:** Find the weight of 25 cubic feet of concrete

weight = volume × density

weight = 25 × 150

weight = 3,750 lbs

**Example:** Find the weight of 3.5 cubic yards of concrete

weight = 3.5 × 4,050

weight = 14,175 lbs
