2Modulus 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. Modulus of elasticity of concrete […]

Get Price2Elasticity of Concrete To calculate the deformation and deflection of structural members we have to know the relation between stress and strain. The relation between stress and strain is of vital interest over the full range in structural design.

Get Price2The value of modulus of elasticity of wet specimen is found higher from 3 to 4 GPa (3.2 to 4.3 x 10 4 kg/cm 2) than dry specimen i.e. the modulus of elasticity of wet concrete is higher by 16.3% to 7.5 according to its compressive strength.

Get Price2A good normal concrete mixture has an E-modulus of 25.000-30.000 N/mm2. 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!

Get Price2The 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 performance concrete will be higher thereby making it a stiffer type of concrete.

Get Price2Modulus of elasticity of concrete is defined as the ratio of stress applied on the concrete to the respective strain caused. The accurate value of modulus of elasticity of concrete can be determined by conducting a laboratory test called compression test on a cylindrical concrete specimen.

Get Price2MODULUS OF ELASTICITY OF CONCRETE The modulus of elasticity of concrete E c adopted in modified form by the ACI Code is given by With normal-weight normal-density concrete these two relations can be simplified to where E c = modulus of elasticity of concrete lb/in 2 (MPa); and = specified 28-day compressive strength of concrete lb/in 2 (MPa).

Get Price2The modulus of elasticity of concrete is a function of the modulus of elasticity of the aggregates and the cement matrix and their relative proportions. 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 ...

Get Price2The modulus of elasticity of concrete in general refers to the ratio of the applied stress on the concrete to the strain-induced. The test for determining the modulus of elasticity of the concrete is known as a compression test on the cylindrical concrete sample.

Get Price2The elasticity of concrete is relatively constant at low stress levels but starts decreasing at higher stress levels as matrix cracking develops. Concrete has a very low coefficient of thermal expansion and as it matures concrete shrinks. All concrete structures will crack to some extent due to shrinkage and tension.

Get Price2Since concrete is a multiphase solid no direct relationship can exist between its density and modulus as in single-phase solids such as metals. The modulus is influenced by density porosity mix proportion moduli of elasticity of the ingredients and the characteristics of the transition zone.

Get Price2Ec = Modulus of elasticity of concrete. f’c = Compressive strength of concrete. According to. ACI 318–08 (Normal weight concrete) the modulus of elasticity of concrete is Ec =4700 √f’c Mpa and; IS:456 the modulus of elasticity of concrete is 5000√f’c MPa. The main factors which may affect the values determination of modulus of ...

Get Price2Elastic modulus is a fundamental parameter in designing concrete structures. In recent years building specifications have even required a specific elastic modulus of concrete to be met mostly to ...

Get Price2Modulus of Elasticity of Concrete. 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. The strength of concrete is dependent on the relative proportion and modulus of elasticity of the aggregate.
