1.1 This test method covers measurement of the changes in height of hydraulic-cement grout by the use of 75 by 150-mm (3 by 6-n.) cylinders, when the cylinders are protected so that the tendency to change in height does not include evaporation so as to cause drying, uptake of moisture, carbonation, or exposure to temperatures outside the range 23 177; 2.0176C (73 177;3176F) or, optionally, to another specified temperature controlled within 177; 2.0176C (177 3176;F).
1.2 If desired, this test method can be adapted to studies of changes in height involving either schedules or environmental treatment different from the standard procedures prescribed by this test method.
1.3 The values stated in inch-pound units are to be regarded as the standard.
1.4 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.
