ASTM C469-02

Standard Test Method for Static Modulus of Elasticity and Poisson's Ratio of Concrete in Compression

SCOPE
1.1 This test method covers determination of (1) chord modulus of elasticity (Young's) and ( 2) Poisson's ratio of molded concrete cylinders and diamond-drilled concrete cores when under longitudinal compressive stress. Chord modulus of elasticity and Poisson's ratio are defined in Terminology E 6.
1.2 The values stated in inch-pound units are to be regarded as the standard.
1.3 This standard does not purport to address all of the safety concerns, if any, associated with its use. It is the responsibility of the user of this standard to establish appropriate safety and health practices and determine the applicability of regulatory limitations prior to use.
