To calculate the weight of concrete, you’ll need the volume and density of concrete. The formula is: Weight = Volume × Density. The density of concrete is typically around 2400 kg/m³.

There are various concrete structure like slab, beam, column, cube, cylinder, blocks, pile, etc are made by mixing of gravel, sand and cement in required proportion to achieve a specific compressive strength, important ingredient that determine the weight of concrete is size and density and amount of sand and gravel used in concrete mix, if dense gravel is used in concrete mix that increase the weight of concrete.

Concrete is categorised into three category a heavy weight concrete, medium weight concrete and lightweight concrete according to size and amount of gravel used in concrete mix, there are different ratio of concrete mix are used to make different types of concrete structure according to their targeted compressive strength.

The weight of concrete determined by its density which can vary based on the amount of gravel, water, sand, cement and air in the mix, density of concrete is the ratio of mass to the unit volume represented as density = mass × volume, and mass of concrete determined by multiplying the volume and density of concrete structure such as mass = volume × density.

**Hence,**

**Density = mass ÷ unit volume**

**Mass = volume × density**

In this regard, “how much concrete weigh”, according to imperial or us customary measurement system, a typical concrete weighs around 4050 lbs per cubic yard, 150 lbs per cubic foot, 1.39 oz per cubic inch, 2.4 gram per cubic centimeter, 24 kN per cubic metre, 2.4 kg per litre, or 2400 kg per cubic metre.

**Calculate weight of concrete**

Calculate weight of concrete you can choose specific measurement units based on Imperial or US customary measurement system, you can determined weight of concrete in following steps:-

**Total weight = Volume × density**

**Now you can calculate weight of concrete cylinder in following steps:-**

1) A concrete cylinder of diameter 150mm and height of 300mm or D= 6″ and H= 12″

2) Convert all dimension of concrete cylinder in feet as D= 0.5 feet and H= 1 feet

3) calculate volume of concrete cylinder as volume = (π D^2/4) × H, V = (3.14 × 0.5× 0.5/4)× 1 = 0.19625 cubic feet

4) calculate weight of concrete cylinder by multiplying volume and their density in similar unit as Weight = Volume× density, density= 150lb/ c f, so total weight = 0.19625 c f × 150 lb/c f = 29.44 pounds or 13.35 kgs.

**4) FOR CONCRETE PILE**

We can calculate weight of concrete pile estimated by multiplying the volume of pile and density of concrete, the volume of square concrete pile is simply represented as Area (V = Area × depth) times the depth. There is 12 inch square concrete pile of length 20 feet.

Now you can calculate weight of concrete pile in following steps:-

1) A concrete pile of dimension 20 feet long and side of square pile 12″

2) Convert all dimension of concrete pile in feet as length = 20 ft and side = 1 feet

3) calculate volume of concrete pile as volume = 1 ft × 1 ft × 20 ft = 20 cubic feet

4) calculate weight of concrete pile by multiplying volume and their density in similar unit as Weight = Volume× density, density= 150lb/ c f, so total weight = 20 c f × 150 lb/c f = 3000 pounds or 1.5 short tons.

**5) FOR CONCRETE COLUMN**

We can calculate weight of concrete column estimated by multiplying the volume of column and density of concrete, the volume of rectangular concrete column is simply represented as Area (V = Area × depth) times the depth. There is 9″× 12″ size rectangular concrete column of length 18 feet.

**Now you can calculate weight of concrete column in following steps:-**

1) A concrete column of 18 feet height and their size is 9″× 12″

2) Convert all dimension of concrete column in feet as height = 18 ft and size = 0.75× 1 in feet

3) calculate volume of concrete column as volume = 0.75 ft × 1 ft × 18 ft = 13.5 cubic feet

4) calculate weight of concrete column by multiplying volume and their density in similar unit as Weight = Volume× density, density= 150lb/ c f, so total weight = 13.5 c f × 150 lb/c f = 2025 pounds or 1.0125 short tons.
