**Density of Cement sand and aggregate in Kg/m3 | list of material density | density of concrete, **hi guys in this article we know about density of construction material like cement, sand, aggregate, cement mortar, concrete, RCC concrete, brick, AAC Block, fly ash brick,steel and other materials in different measuring unit like kg/m3, lb/ft3 and g/cm3 and their unit weight.

**Density of Cement sand and aggregate in Kg/m3 | list of material density**

**Density** is described as Unit Weight of material, another word weight of material comprising volume in specific unit. Knowing density of different material it is quite easy to calculate weight of given material in construction line.

The **density** of a substance is its mass per unit volume. The symbol most often used for finding density is ρ (the lower case Greek letter rho), although the Latin letter D can also be used. Generally density is defined as mass divided by volume.

Density of material like cement sand and aggregate and other substance which are extensively used in construction line are measured in their specific unit **kg/m3,g/m3,lb/ft3 and kg/ft3.**

**density of material can be expressed as**

p = m/V = 1/v

Where

p = density (measured in kg/m3,g/cm3,lb/ft3 and kg/ft3)

m = mass (measured in kg and gram

V = volume (measured in m3 and cft

And knowing important conversion factor

Conversion: 1 kg / m3 = 0.0624 lb / ft3.

**Density of cement**

The cement is a binder and adhesive material extensively used in construction line like building formation, super structure,multi storey building, over bridge, dams and other civil structure. It hardens and adheres to other materials to join them together. Cement is rarely used on its own, but to strong bond sand and gravel.

**Cement density:- generally density of cement is around 1440kg/m3** or it is measured in other unit- their density is 1.440 in g/cm3, 94 in lb/ft3 and 14.40 in kn/m3.

The cement mixed with fine aggregate produces cement mortar for masonry, or with sand and gravel produces concrete.

● Ans. 1440 kg/m3 is density of cement

**Density of cement in kg/m3**

Density of cement measured in Kg/m3 (kilograms/cubic meter) such as density is the ratio of mass to volume, so density of cement in kg/m3 is 1440, in other word, 1440 kg/m3 is density of cement.

● Ans. 1440 is density of cement in Kg/m3 (kilograms per cubic metre).

**Now discuss density of cement in different measuring unit like g/cm3, lb/ft3 and kg.**

**Density of cement in g/cm3**

Density of cement = 1440kg/m3, then density of cement in g/cm3 = 1440/ 1000 = 1.440, so 1.440 is density of cement in g/cm3.

**Density of cement in lb/ft3**

● **density of cement in lb/ft3:** density of cement measured in foot pound system, and we know conversion factor: 1 kg / m3 = 0.0624 lb / ft3, then density of cement in lb/ft3 = 0.0624 ×1500 = 94, so 94 is density of cement in lb/ft3.

**Density of cement in kg**

**Density of cement in kg:** we know that Unit Weight of density is 1440 kg/m3, it means one cubic metre volume of cement weight in kg is 1440, so 1440 is density of cement in Kg.

**Density of cement in kN/m3**

**Density of cement in kN/m3:** we know that 1kN/m3 = 1000 N/m3 and 1kg/m3 = 10 N/m3, so 1440 kg/m3 = 14400 N/m3, now find out density of cement in kN/m3 = 1440/100 = 14.40, so density of cement in kN/m3 is 14.40.

● density of dry cement is 1440 kg/m3 and density of cement bag is 1440 kg/m3.

**Density of aggregate (coarse sand)/ gravel**

The aggregate (coarse sand)/ gravel is an aggregation of non-metallic minerals obtained in the form of particles and can be processed and used in the construction of civil and road engineering.

**Aggregate density**:- density of coarse sand/ gravel/ aggregate is ranging between 1450 – 2082 kg/m3 in metric system or 75 – 110 lb/ ft^3 based in Imperial and US customary measurement system depending on different condition like wet, dry, loose, dry packed and wet packed.

Aggregates Are Mainly Classified into Two Categories: 1)Fine aggregate (10mm) and 2) Coarse aggregate (20 mm and 40mm).

The **fine aggregate** is natural sand that has been washed and sieved to remove particles larger than 5 mm, and the coarse aggregate is a gravel that has been crushed, washed and sieved so that the particles vary from 5 to 50 mm in size. The fine and coarse aggregate is delivered separately.

As they need to be sieved, a prepared mixture of fine and coarse aggregate is more expensive than the natural all-in aggregate.

The reason for using a mixture of fine and coarse aggregate is that by combining them in the correct proportions, concrete with very few voids or spaces can be made, and this reduces the amount of comparatively expensive cement needed to produce strong concrete.

**Density of aggregate in kg/m3**

Bulk Density of the Aggregate

The apparent density or unit weight of an aggregate is the Mass or weight of the aggregate needed to fill a container with a specified unit volume.

**Density of aggregate in kg/m3**:- the approximate apparent density of the aggregate that is commonly used in normal-weight concrete work is between 1200-1750 kg/m3, but for estimating purpose it would be taken as 1500 kg/m3 by Builders and contractors.

**Bulk density = Mass / volume**

If the volume is one unit, Bulk density = Mass.

In this definition, the volume contains the aggregates and the voids between the aggregate particles.

**Density of gravel in lb/ft^3**

**Density of gravel in lb/ft^3**:- the approximate apparent density of the aggregate/gravel that is commonly used in normal-weight concrete work is between 75 -110 lb/ ft^3, but for estimating purpose it would be taken as 110 lb/ft^3 by Builders and contractors.

**Density of gravel in lb/yd^3**:- the approximate apparent density of the aggregate/gravel that is commonly used in normal-weight concrete work is between 2025 -3000 lb/ yd^3, but for estimating purpose it would be taken as 3000 lb/yd^3 by Builders and contractors.

Here, the standard test method for determining the apparent density of aggregates is presented in the ASTM C 29 (AASHTO T 19) standard.

**● The relative density of aggregate:**

the relative density (specific gravity) of an aggregate is the ratio between its Mass and the Mass of an equal volume of water.

**Relative density = Mass of the aggregate / Mass with an equal volume of water**

Most aggregates have a relative density between 2.4-2.9 with a corresponding particle density (Mass) of 2400-2900 kg/m3 (150-181 lb /ft3).

Here, for coarse aggregates, the standard test method was explained in ASTM C 127 (AASHTO), and, for fine aggregates, the standard test method was explained in ASTM C 128 (AASHTO).

The relative density of an aggregate can be determined on an oven-dried basis or on a dry saturated surface (SSD).
