According to the "Structural Engineer's Pocket Book" concrete commonly has a modulus of elasticity in the range of 17 - 30 GPa.
The exact value of modulus of elasticity depends on the concrete's uniaxial compressive strength after a cure time of 28 days.
These values are related using the following:
Emc = 4700 x sqrt(UCS)
Where:
Emc = Elastic Modulus (MPa)
UCS = Uniaxial Compressive Strength of Concrete after 28 days (MPa).

This varies greatly but is normally conservatively taken as 30Gpa
It can be calculated as 57000 * Sqrt (fc')
It's 5000 I think
The modulus of elasticity of concrete is denoted by Ec .Ec = 5000 sqrt fck as per IS standardswhere, fck- The compressive strength of concrete at 28 days in N/mm2 .
5000x (fck)*power(1/2) =5000x5 =25000 N/mm2
30-100 Gpa (in compression)
how does the fineness modulus of aggregate affect the strength of concrete
Stiffness is defined as the ratio of load per unit deformation.
According to IS 456-2000 the value is square root of 5700fck
IN MACHINE design modulus of elasticity place an important role. from the value of modolus of elasticity we come to know about maximum value of load that can be to the given material upto which the material is assume to follow the hook's law.

130 gpa
Young's modulus
applications of modulas of elasticity As the term implies, "Modulus of Elasticity" basically relates to the elasticity or "flexibility" of a material. The value of modulus of elasticity are very much significant relating to deflection of certain materials used in the construction industry. Take for example the general E value of mild carbon steel is about 200 GPa compared to about 70 GPa for aluminum. This simply translate that aluminum is 3 times flexible than steel.
5000x (fck)*power(1/2) =5000x5 =25000 N/mm2
the dimensions of Young's Modulus of Elasticity = (M).(L)^(-1).(T)^(-2)
Young's modulus
When we talk about deformatation, we are referring to two properties, namely Elasticity and Plasticity. These properties are measured using constants known as " Moduli of Elasticity". There are 4 such moduli: Young's Modulus Axial Modulus Rigidity Modulus Bulk Modulus The larger the value of the Bulk Modulus, the harder it is to compress the material.
Modulus of elasticity will be 2.06*10^5 N/mm2
there are different types of modulus it depends on what types of stress is acting on the material if its direct stress then then there is modulus of elasticity,if tis shear stress then its modulus of rigidity and when its volumetric stress it is bulk modulus and so on
