High Performance Concrete Modulus of Elasticity
The modulus of elasticity is a very important mechanical property of concrete. The higher the value of the modulus, the stiffer the material is. Thus, comparing a high performance concrete to a normal strength concrete, it is seen that the elastic modulus for high

Determination of Elastic Modulus of Concrete in …
Modulus of elasticity of concrete is the ratio of normal stress to the corresponding strain for tensile or compressive stresses below the proportional limit of concrete, ACI 318-14. The value of elastic modulus of concrete can be obtained using formulas provided by different codes, but the values may not be accurate. The accurate value of […]
Modulus Of Elasticity
· Elastic modulus of concrete is not easy to determine, because of non-linear behavior of concrete. Concrete is very strong in compression but very weak in tension and this is the main reason for non-linear behavior of concrete. To overcome this effect, concrete is use with reinforcing bars, which changes the behavior of concrete from brittle to ductile behavior. when this case happens then

Short Term Loading
· Modulus of elasticity “the slope of the initial tangent straight line” depends on the strength of the material. In case of high strength concrete, it is seen to be larger. This is because, a high strength concrete has less number of strains before failure. High strength
Youngs modulus of concrete Calculator
Youngs modulus of concrete calculator uses Young’s modulus of concrete=5000*(Characteristic compressive strength^(1/2)) to calculate the Young’s modulus of concrete, The Youngs modulus of concrete formula is defined as ( the stress required to produce unit
Young’s modulus
Young’s modulus, the Young modulus or the modulus of elasticity in tension, is a mechanical property that measures the tensile stiffness of a solid material. It quantifies the relationship between tensile stress (force per unit area) and axial strain (proportional deformation) in the linear elastic region of a material and is determined using the formula: [1]
