The modulus of elasticity of concrete may be measured in compression, tension or shear. The modulus of elasticity in tension is equal to the modulus of elasticity in compression. Stress-Strain Relationship of Aggregate and Cement Paste: The curve drawn between stress and strain of aggregate alone is found a fairly good straight line.

The modulus of elasticity of concrete is relatively constant at low stress levels but starts decreasing at higher stress levels as matrix cracking develops. The elastic modulus of the hardened paste may be in the order of 10-30 GPa and aggregates about 45 to 85 GPa. The concrete composite is then in the range of 30 to 50 GPa.

Elastic modulus of concrete can be classified into two main groups as: 1. Static modulus. 2. Dynamic modulus.

Article Google Scholar Ultrasonic measurements provide values of E‐modulus that are higher than the values provided by the quasi‐static tests at the time of the concrete setting. Similar mechanisms associated to very short term creep could explain the difference between the quasi‐static and high‐frequency elastic modulus. Elastic modulus test of concrete 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.

Aggregate impact value test- step by Step Procedure with Report concrete i.e., the static modulus of elasticity does not truly represent the elastic behaviour of concrete due to the phenomenon of creep. The elastic modulus of elasticity will get affected more seriously at higher stresses when the effect of creep is more pronounced. Concrete and reinforcement properties. For the plain concrete we will assume a Young's modulus E = 28300 MPa, a Poisson's ratio = 0.2 , and a compressive strength f c = 37 MPa. For the steel of the bar reinforcements we assume Von Mises plasticity with work hardening, a Young's modulus E = 2.1 x 10 5 MPa and a yield stress = 380 MPa. Young's Modulus or Tensile Modulus alt. Modulus of Elasticity - and Ultimate Tensile and Yield Strength for steel, glass, wood and other common materials Sponsored Links Tensile Modulus - or Young's Modulus alt. Modulus of Elasticity - is a measure of stiffness of an elastic material.

The equation for “ G ” is: Note. If you enter a value for Shear Modulus that does not match the value calculated using the above equation you will be given a warning. 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.
