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 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.

Solids liquids and gases. which ones are hard to deform?

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.

What are the different types of modulus elasticity?

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
