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).

What is the modular ratio of m20?
The modular ratio is the ratio of the modulus of elasticity of steel to the modulus of elasticity of concrete. For M20 concrete, which typically has a characteristic compressive strength of 20 MPa, the modulus of elasticity is generally assumed to be around 25 GPa. If we consider the modulus of elasticity of steel to be approximately 200 GPa, the modular ratio (n) can be calculated as n = E_steel / E_concrete, resulting in a modular ratio of about 8. This means that the stiffness of steel is roughly eight times that of M20 concrete.

What is the definition of modulus of elasticity?
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.

What is modular ratio of concrete?
The modular ratio of concrete is a measure used in structural engineering to relate the elastic moduli of concrete to that of reinforcing steel. It is defined as the ratio of the modulus of elasticity of steel to the modulus of elasticity of concrete. This ratio helps engineers determine how much the two materials will deform under load and is crucial for analyzing the behavior of reinforced concrete structures. Typically, the modular ratio for concrete is around 8 to 12, depending on the specific types of concrete and steel used.
