The density of different construction materials plays a crucial role in maintaining structural strength and integrity. The density of a material can be described as the mass of the material per unit volume or the unit weight of the material. In this article, we will discuss the density of a long list of construction materials, including sand, cement, aggregate, concrete, cement motor, RCC concrete, steel, brick, fly ash brick, ACC Block, and other important construction materials in various measuring unit units, such as Kg/m3, lb/ft3, and KN/m3.

Density of Cement Sand and Aggregate in Kg/m3 | List of Material Density

Density is also known as the unit weight of the material which means how much a material weighs per unit volume. This is why if you know the density of the construction materials, you can easily calculate the weight of the materials.

Mathematical Expression of Density:

Density represents the mass of the material per unit volume.

Therefore, the mathematical expression of density is –

Density (ρ) = Mass (m) / Volume (V)

            ρ = m/V

Some extensively used measuring units for density are Kg/m3, g/cm3, lb/ft3, and KN/m3, where Kg, g, lb, KN are the measuring units of mass and m3, cm3, and ft3 are the units of volume.

Let’s take a look at the below table to know the density of cement sand and aggregate in Kg/m3 and other units.

Density of Cement

Cement has a significant application as an adhesive material in various types ofconstruction, such as the formation of buildings, multi-storey buildings, dams, superstructures, over-bridges, and other civil structures. The adhesive property of the cement helps it stick to other materials, such as gravel and sand and builds a strong bond with the material once it hardens.

The density of cement in Kg/m3 is 1440 Kg/m3.

The density of cement in g/cm3 is 1.440 g/cm3.

[Calculation: 1 Kg/m3 = 1000g/ (100×100×100) cm3 = 1/1000 g/cm3
            Therefore, 1440 Kg/m3 =1440/1000 g/cm3 = 1.440 g/cm3]

The density of cement in lb/ft3 is 90 lb/ft3.

[Calculation: 1 Kg/m3 = 0.0624 lb/ft3
            Therefore, 1440 Kg/m3 = (1440×0.0624) lb/ft3 = 89.856 lb/ft3 = 90 lb/ft3 (approximately).]

The density of cement in KN/m3 is 14.40 KN/m3.

[Calculation: 1 KN/m3 = 1000 N/m3; whereas, 1 Kg/m3 = 10 N/m3
            Therefore, 1440 Kg/m3 = 14400 N/m3 =14400/1000 KN/m3 =14.40 KN/m3]

                                                Density of Cement Mortar

The mixture of cement and fine sand forms cement mortar. This cement mortar is useful for brickwork and plastering. However, depending on the brickwork and plastering, the ratio of sand and cement in the mixture can be different. This is why the density of the cement mortar can slightly vary from one type of construction to another. Usually, the weight commonly used cement mortar in 1 cube meter is 2162 Kg. Therefore, the density of the cement mortar is 2162 Kg/m3.

The density of cement mortar in Kg/m3 is 2162 Kg/m3.

The density of cement mortar in g/cm3 is 2.162 g/cm3.

[Calculation: 1 Kg/m3 = 1000 g/ (100×100×100) cm3 = 1/1000 g/cm3
            Therefore, 2162 Kg/m3 = 2162/1000 g/cm3 = 2.162 g/cm3]

The density of cement mortar in lb/ft3 is 135 lb/ft3.

[Calculation: 1 Kg/m3 = 0.0624 lb/ft3
            Therefore, 2162 Kg/m3 = (2162×0.0624) lb/ft3 = 134.9088 lb/ft3 =135 lb/ft3 (approximately).]

The density of cement mortar in KN/m3 is 21.62 KN/m3.

[Calculation: 1 KN/m3 = 1000 N/m3; whereas, 1 Kg/m3 = 10 N/m3
            Therefore, 2162 Kg/m3 = 21620 N/m3 =21620/1000 KN/m3 =21.62 KN/m3]

                                             Density of Cement Concrete

The mixture of cement, sand, and aggregate is called plain cement concrete. The cement concrete is useful for PCC work, RCC work, and concreting, such as beam, column, slab, and footing. The density of plain cement concrete (PCC) and reinforced cement concrete (RCC) is slightly different. Whereas the density of plain cement concrete is approximately 2400 Kg/m3, reinforced cement concrete has the density of 2500 Kg/m3.

The density of cement concrete (PCC) in Kg/m3 is 2400 Kg/m3.

The density of cement concrete (PCC) in g/cm3 is 2.4 g/cm3.

[Calculation: 1 Kg/m3 = 1000 g/ (100×100×100) cm3 = 1/1000 g/cm3
            Therefore, 2400 Kg/m3 = 2400/1000 g/cm3 = 2.4 g/cm3]

The density of cement concrete (PCC) in lb/ft3 is 150 lb/ft3.

[Calculation: 1 Kg/m3 = 0.0624 lb/ft3
            Therefore, 2400 Kg/m3 = (2400×0.0624) lb/ft3 = 149.76 lb/ft3 = 150 lb/ft3 (approximately).]

The density of cement concrete (PCC) in KN/m3 is 24.00 KN/m3.

[Calculation: 1 KN/m3 = 1000 N/m3; whereas, 1 Kg/m3 = 10 N/m3
            Therefore, 2400 Kg/m3 = 24000 N/m3 =24000/1000 KN/m3 =24.00 KN/m3]

                                                Density of Sand

Depending on the condition of the sand, its density varies. For instance, the density of the packaged sand is different from the loose sand. In the packaged sand, the sand grains create a narrower formation, resulting in increased density. Similarly, the wet sand has a different density than the dry sand.

The density of the sand depending on its condition, such as loose, packed, wet, dry, dusty, and wet packed, usually ranges from 1450 to 2082 Kg/m3. The most commonly used sand in the construction work has the density of 1600 Kg/m3. The density of the coarse sand also ranges from 1450 to 2082 Kg/m3. The density of river sand is approximately 1710 Kg/m3, whereas, the crush sand or M sand has the density of 1750 Kg/m3. Let’s take a look at the below table to understand how the density of sand differs depending on its condition-

Sand TypeDensity in Kg/m3Density in g/cm3Density in lb/ft3Density in KN/m3
Loose Sand1442 Kg/m31.442 g/cm390 lb/ft314.42 KN/m3
Dry Sand1602 Kg/m31.602 g/cm3100 lb/ft316.02 KN/m3
Packed Sand1682 Kg/m31.682 g/cm3105 lb/ft316.82 KN/m3
Wet Sand1922 Kg/m31.922 g/cm3120 lb/ft319.22 KN/m3
Wet Packed Sand2082 Kg/m32.082 g/cm3130 lb/ft320.82 KN/m3

Therefore, the density of sand in Kg/m3 ranges from 1442 to 2082 Kg/m3.

The density of sand in g/cm3 ranges from 1.442to 2.082 g/cm3.

The density of sand in lb/ft3 ranges from 90 to 130 lb/ft3.

The density of sand in KN/m3 ranges from 14.42 to 20.82 KN/m3.

Density of Aggregate (Coarse Sand/Gravel)

The aggregates or gravels are the combination of non-metallic minerals that are found in the form particles. The aggregates are useful to provide strength in road and civil engineering constructions. The density of the aggregate also depends on its conditions, such as dry, wet, loose, packed, wet packed, and the size of the particles. The density of commonly used aggregates usually ranges from 1200 to 1750 Kg/m3.

There are mainly two types of aggregates, such as I. Fine Aggregate (less than 5mm), and II. Coarse Aggregate (5-50 mm). Whereas the fine aggregates are naturally found sand which is washed and filtered to eliminate the particles bigger than 5 mm, the coarse aggregates are crushing the gravels and then washing and sieving them to get the particles ranges from 5 to 50 mm in size. Some constructions involve the mixture of fine and coarse aggregates with correct proportions to reduce voids, the use of expensive cement, and make the concrete stronger.

The Size of the AggregateDensity in Kg/m3Density in g/cm3Density in lb/ft3Density in KN/m3

40 mm1200 Kg/m34.200 g/cm375 lb/ft312.00 KN/m3

The Density of aggregate in Kg/m3 ranges from 1200 to 1750 Kg/m3.

The Density of aggregate in g/cm3 ranges from 1.200 to 1.750 g/cm3.

The Density of aggregate in lb/ft3 ranges from 75 to 109 lb/ft3.

The Density of aggregate in KN/m3 ranges from 12.00 to 17.50 KN/m3.
