This test method is intended to provide a means of assessing the ability of a hydraulic-cement grout to retain a stable volume during the stipulated testing period of 28 days, provided that the tendency to change height does not include the effects of drying caused by evaporation, uptake of moisture, carbonation, or exposure to temperatures outside the range 23.0 ± 2.0 °C (73 ± 3 °F) (Note 1). An exception is made when the options described in the section on test conditions are exercised.

Note 1—This test method does not measure the change in height before hardening (see Test Method C827).

1. Scope

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-in.) 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 ± 2.0 °C (73 ± 3 °F) or, optionally, to another specified temperature controlled within ± 2.0 °C (± 3 °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 SI 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.
