Standard Test Method for Static Modulus of Elasticity and Poisson's Ratio of Concretein Compression1
1. Scope*
1.l This test method covers determination of () chordmodulus of elasticity (Young's) and (2) Poisson's ratio ofmolded concrete cylinders and diamond-drilled concrete coreswhen under longitudinal compressive stress.Chord modulus ofelasticity and Poisson's ratio are defined in Terminology E6.
1.2 The values stated in cither Sl units or inch-pound unitsare to be regarded separately as standard.The values stated ineach system may not be exact equivalents;therefore，eachsystem shall be used independently of the other.Combiningvalues from the two systems may result in non-con巴复制with the standard.
1.3 This standard does not purport to address all of thesafety concerns，if any,associated with its use. It is theresponsibility of the user of this standard to establish appro-priate safety and health practices and determine the applica-bilisy of regaulatory limitations prior to use.
