Please note that the higher the E-module, the higher peak stresses will become! Which means that the higher the E-module in concrete, the sooner cracks will appear! Modulus of Elasticity of Concrete can be defined as the slope of the line drawn from stress of zero to a compressive stress of 0.45f’ c. As concrete is a heterogeneous material.

High-E designs provide high compressive strength, reduced creep (movement of the concrete over time) and higher stiffness. 2.3 Elastic Modulus of Concrete 2.3.1 Definition and Determination of Elastic Modulus of Concrete The modulus of elasticity or "Young's Modulus", a very important mechanical property reflecting the capability of concrete to deform elastically, is defined as the slope of the stress-strain curve within the proportional limit of a material. Elastic modulus test of concrete
The elastic modulus of concrete is required for the design of reinforced concrete structures, including in predicting creep deformation. Current models that estimate the elastic modulus (E), primarily on the basis of concrete compressive strength, vary in their accuracy and have hence proved to be inadequate to apply to the wide range of concretes.

High-E designs provide high compressive strength, reduced creep (movement of the concrete over time) and higher stiffness. The variations are linear in case longitudinal modulus of elasticity E L and nonlinear variation for transverse young’s modulus of elasticity E T. As shown in figure 4 , for any grade of concrete i.e., M40, M60 and M120, the longitudinal young’s modulus of elasticity showed 0.125% incremental value for SWNT.
