Frost damage in concrete is caused by the volume expansion of freezing water as tensile and compressive strength and elastic modulus of concrete, but also,

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.

2017-01-22 · Concrete generally have an elastic modulus varying between 30 to 50 GPa. The factors affecting elastic modulus of concrete are: 1- Coarse aggregate properties- like elastic modulus of aggregate, My understanding is that since E = stress / strain, a higher E means a stiffer material, b/c it takes more force to produce the same amount of strain. I was surprised to learn that Elasticty for concrete (24 GPa) is an order of magnitude smaller than that of steel (200 GPa).

Calculate the theoretical values the Young’s Modulus and Poisson’s ratio. Calculation Procedures Young’s Modulus – E=(s 1-s 2)/(e 2-.000005) s 1 =the stress corresponding to the longitudinal strain of 50 micro strain. MEASURING THE MODULUS OF ELASTICITY OF CONCRETE CORES AND CYLINDERS Rev. 0 1 1. PROCEDURE OVERVIEW The determination of the modulus of elasticity for cylindrical concrete samples such as molded cylinders and drilled cores is outlined in this procedure.

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.
