What is the density of concrete?

What is the density of concrete?

The density of concrete varies, but is around 2,400 kilograms per cubic metre (150 lb/cu ft). Reinforced concrete is the most common form of concrete.

How much does unreinforced concrete weigh?

A normal weight concrete weighs 2400 kg per cubic meter or 145 lbs per cubic foot (3915 lbs per cubic yard). The unit weight of concrete (density) varies depending on the amount and density of the aggregate, the amount of entrained air (and entrapped air), and the water and cement content.

What is the density of 25 Mpa concrete?

Density – ρ : 2240 – 2400 kg/m3 (140 – 150 lb/ft3)

How do you calculate the density of concrete?

Density Calculation Steps

  1. Weigh the container with the concrete (2) – record value to nearest tenth of a pound.
  2. Subtract the empty container weight from the full container weight (2) – (1) = weight of concrete (3)
  3. Divide the weight of concrete by the known volume (3) / (4) = density, or fresh unit weight.

Why is density of concrete important?

The mechanical properties of concrete are highly influenced by its density. A denser concrete generally provides higher strength and fewer amount of voids and porosity. So water absorption will also be less and better durability is expected from this type of concrete.

What is the density of RCC concrete?

Density of Different Construction Materials.

Materials Name Density
PCC 2400 kg/m3
RCC 2% Steel 2500 kg/m3
Cement concrete block(solid) 1800 kg/m3
Lime Mortar 1760 kg/m3

What is the standard density of normal concrete?

Standard Values of Concrete Density. We have found the following sources where the standard value of the density of concrete is provided. The density of normal concrete is 2400 kg/m 3 (150 pcf or lb/ft 3 ) and the density of lightweight concrete is 1750 kg/m 3 (110 pcf or lb/ft 3 )

Is the density of reinforced concrete too high?

However 26 kN/m³ for wet reinforced concrete in typical composite slabs is excessive and unreasonable, if only because the reinforcement content is below average.

What should be the volume of hardened concrete?

“Volume generally assumed for the density of hardened concrete is 150 lb./ft 3. (2400 kg/m 3)”. 2400 kg/m 3. Concrete is an artificial material similar to stone that is used for many different structural purposes.

What are the physical properties of reinforced concrete?

General material properties for reinforced concrete according to EN1992-1-1 §3.1 Material Property Value Density ρ ≈ 2500 kg/m 3 Unit weight γ ≈ 25.0 kN/m 3 Modulus of elasticity Ecm (secant value see table above Shear modulus G (in the elastic range) G = E / [2 ⋅ (1 + ν) ]
