ASTM C801-98 PDF

Scope: 1.1 This test method covers the procedures for testing hardened concrete when subjected to triaxial stress conditions. Materials other than concrete, cement paste, or mortar are excluded. When the determination of the strength of concrete under a triaxial state of stress is made according to this test method, two of the three principal stresses are always equal. There is no provision made for the measurement of pore pressures; therefore all strength values are in terms of total stress. 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 problems, 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.
