Modulus of elasticity is a measure of stiffness, with higher-modulus materials exhibiting less deformation under load compared to low-modulus materials. When making a repair, the modulus of elasticity should be similar to that of the concrete substrate. This allows for uniform load transfer across a repaired section.
Modulus of elasticity of concrete (Ec) is defined as the ratio of the applied stress to the corresponding strain. Not only does it demonstrate the ability of concrete to withstand deformation due to applied stress but also its stiffness. In other words, it reflects the ability of concrete to deflect elastically.
The Young's modulus of steel (also referred to as modulus of elasticity of steel) is between 190 – 210 GPa at room temperature, which is around 27500 ksi to 31200 ksi. The steel young modulus is a measure of its stiffness/ resistance elastic deformation to tensile loads.
The new version of Hooke's law is . Now we have, which is called Young's Modulus or the modulus of elasticity.Young's modulus provides the linear relationship between stress and strain. Young's modulus is the same for any material–you could take a spoon or a girder; as long as they have the same young's modulus and you knew their sizes, you could predict how much force would cause ...

The greater the value of young's modulus, the stiffer is the material. Units of Modulus of Elasticity/Young's modulus are: Nm -2 or Pa. The practical units used in plastics are megapascals (MPa or N/mm 2) or gigapascals (GPa or kN/mm 2 ). In the United States customary units, it is often expressed as pounds (force) per square inch (psi).
