Test to Determine Modulus of Elasticity of Concrete

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.In the test,the deformation of the specimen with []Stress,Strain,and Elastic Modulus University Physics For a small stress,the relation between stress and strain is linear.The elastic modulus is the proportionality constant in this linear relation.Tensile (or compressive) strain is the response of an object or medium to tensile (or compressive) stress.Here,the elastic modulus is called Youngs modulus.Static and Dynamic Elastic Modulus of Concrete TopicSep 30,2019 effect of cylinder size on the modulus of elasticity and#0183;The American Concrete Institute.Founded in 1904 and headquartered in Farmington Hills,Michigan,USA,the American Concrete Institute is a leading authority and resource worldwide for the development,dissemination,and adoption of its consensus-based standards,technical resources,educational programs,and proven expertise for individuals and organizations involved in concrete
