# The elastic modulus ranged from 2.48 to 7.49GPa what showed that the material is more elastic than ordinary Portland cement concrete. 1 Introduction. Global

20 Dec 2020 Modulus of elasticity (Young's Modulus) is one of the most important mechanical properties of concrete. Modulus of elasticity is defined as the

Normal weight concrete density = 150 lb/ft3 for computing loads 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. computation of mix proportions of concrete given its elastic modulus, E. The computer programs can also determine modulus of elasticity, E, from a given concrete mix proportion. The programs based on simplex theory and regression theory are as presented in Appendix A and Appendix B respectively. And Tables 1 and 2 2016-01-20 · The modulus of elasticity of concrete is known to be influenced by the cement paste, the aggregate's nature, the interfacial transition zone (ITZ) and the compacity of concrete (Neville, 1995). Like other properties, the modulus of elasticity also depends on the age of concrete, as a result of the cement paste stiffening over time. Modulus 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.

The concrete used in Dynamic elastic modulus determined by P-wave velocity measurements has been known to possess the characteristics of concrete, heterogeneous, and porous Estimating the elastic modulus of concrete made with artificially manufactured lightweight aggregates - Author: R.V. Balendran. Results of regression analysis on relationship of elastic modulus to shrinkage strain . 122. 6-4. Correction factors for the ACI 209 model on shrinkage prediction 5 May 2018 Modulus of Elasticity (MOE) is a key parameter in reinforced concrete design. It represents the stress-strain relationship in the elastic range and This paper shows that the elastic modulus of concrete depends on the aggregate used, the compressive strength of the concrete, the aggregate/cement ratio and The modulus of elasticity of concrete is typically calculated from a compressive strength test of a concrete specimen. From these strength tests, stresses and strains The modulus of elasticity of a concrete material is calculated automatically values' is unchecked, the value of the E modulus can manually be edited:.

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 elasticity are, Modulus of elasticity of concrete (Ec) is defined as the ratio of the applied stress to the corresponding strain.
