This concrete weight calculator is for you if you’ve ever needed to determine the weight of concrete per cubic meter. Use concrete calculator to calculate the weight of a certain amount of concrete and discover how much easier your concrete building jobs become. Meanwhile, check our Belt Length Calculator.

What is concrete weight?

Concrete consists of fine and coarse materials held together by a fluid cement paste that hardens (cures) over time. Concrete is the most frequently used building material and the second most widely used substance on the earth, behind water. It is used twice as much as a ton for a ton as steel, wood, plastics, and aluminum combined.

The weight of a common concrete mix is 150 pounds per cubic foot, 4,050 pounds per cubic yard, or 2,400 kilograms per cubic meter. Concrete’s density, which varies depending on the amount of aggregate, water, and air in the mix, determines its weight.

How to use the concrete weight calculator?

Our concrete weight calculator is easy to use and understand. All you have to do now is:

In the concrete calculator, select the concrete type from the first box. The five options are asphalt, gravel, Portland-Limestone, Portland, and reinforced concrete. This is because the densities of these two forms of concrete vary. Because density is one of the parameters that determine the weight of concrete, it has an impact on the subsequent calculation.

Put in the amount of concrete you’ll need (volume). Remember to select a unit that is appropriate for your requirements. You have the option of getting substantial weight per cubic feet, cubic yards, or cubic meters.

In the density box, select the unit you desire. We’ve already entered the proper densities into the calculator to save you time.

After that, the concrete calculator will compute the weight of the concrete based on the information you entered. Remember to double-check the units here as well!

Concrete weight calculator formula and example

The formula for estimating the weight of concrete is rather straightforward. In fact, you’re probably already familiar with it, as it’s the standard weight-loss equation taught in schools! Just in case you forgot, it goes like this:

weight=volume\times density

Let’s go through a small example for clarity’s sake.

Consider the following scenario: we have volume of 15 cubic meters of Portland concrete. Because this type of concrete has a density of 2,300 kilograms per cubic meter, the calculation is as follows:

weight = 15  \; m^3 \times 2.300 \; kg/m^3 = 35.500 \; kg

Types of concrete

You may choose from five different types of concrete using this calculator. Here’s some background about them:

  • Asphalt (density: 2,243 kg/m3 / 140.03 lb/ft3) is a composite material that is extensively used for road paving, airport runways, and embankment dam cores. Asphalt, sometimes known as blacktop or just asphalt, is used for roads and streets because it makes far less noise than other concretes when subjected to traffic. Abbreviation ‘ft’ stands for feet.
  • Gravel (density: 2,404 kg/m3 / 150.01 lb/ft3) – gravel is a type of concrete aggregate. It isn’t concrete in and of itself, but it is frequently utilized as a part of it. It is made up of loose rocks of varying sizes (usually microscopic in the case of concrete).
  • Portland-Limestone (density: 2,371 kg/m3 / 148.02 lb/ft3) is a type of cement created from a special type of limestone that was originally discovered on the Isle of Portland in Dorset. It is one, if not the most costly type of cement, yet it is still in wide use in the construction industry.
  • Due to its widespread availability, Portland (density: 2,300 kg/m3 / 143.58 lb/ft3) is one of the most affordable materials.
  • For ductility and durability, we use reinforced cement concrete (density: 2,500 kg/m3 / 156.07 lb/ft3). It is reinforced with an extra material (most often steel reinforcing bars).

FAQ

How long should concrete cure before putting weight on it?

Keep this in mind while waiting for concrete to dry: the forms may be removed after the initial set, and people can walk on the surface for 24 to 48 hours. After a partial cure, traffic from autos and equipment is fine after 7 days. The concrete should be completely cured after 28 days.

How do you calculate concrete weight?

The weight of a concrete slab may be determined by calculating the slab’s volume (V) and multiplying it by the concrete’s density (D). We find the volume is by multiplying the area (A = L x W) by the depth (D), where W is the slab’s total weight.

What does 1 cubic meter of concrete weigh?

Concrete weights 2.5 tons per cubic meter. 350 kilograms of cement, 700 kilograms of sand, 1,200 kilograms of chippings, and 150 liters of water make up a 1 m3 of concrete.

Is concrete heavier than water and density of concrete?

The density of concrete varies based on its composition, but average density of concrete is around 2,400 kilograms per cubic meter (150 pounds per cubic foot). Because a cubic foot of fresh water only weighs 62.4 pounds and exerts less upward force, its apparent weight would be 87.6 pounds.
