![]() Since the density is known, the formula for mass can be changed by multiplying the density by the volume. The density of concrete is determined by mass and volume. Step Two: Determine the Weight of Concrete ![]() For instance, the preferred concrete mix for a countertop will have less aggregate than the mix for a driveway or footing because the countertop does not need to be as strong, which will affect the density and, thus, the weight of the concrete.ĭensity of concrete in different units of measure Volume The density of a typical concrete mix is 2.4 g/cm 3 or 150 lbs/ft 3.ĭifferent mixes of concrete will use more or less aggregate as well. For instance, gravel has a much higher density than vermiculite. ![]() You will need to know the precise type of concrete and aggregate you are using for the most accurate weight. Some concrete mixtures use different levels and types of aggregate. Most concrete will contain some amount of aggregate in the form of gravel or stone, which are added for strength. The density of concrete is 3.15 g/cm 3, while the density of aggregate will vary by the type of stone used. Step One: Determine the Density of Concreteĭensity is the measure of mass for a given volume and is defined by the formula: Since the weight is determined by the density and volume, the first step is to calculate the density, then calculate the weight. It’s a time-saving solution that eliminates the need. Simply input the dimensions and spacing of the rebar, and our calculator will provide you with the total weight. Using our rebar weight calculator is straightforward. You can calculate the weight of concrete in a few easy steps. Our rebar weight calculator is a handy tool that allows you to efficiently calculate the weight of rebar for your projects.
