The maximum change in height will be reported, maximum decrease, maximum increase, change in height at set time and change in height at conclusion of test. Astn 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.
Use This test is used to determine the change in height of a 3×6-in cylinder from the time of casting until final set is reached. These notes and footnotes shall not be considered as requirements of the test method. It is particularly applicable to grouting, patching, and form-filling operations where the objective is to completely fill a cavity or other defined space with a c27 mixed cementitious mixture that will continue to fill the same space at time of hardening.

Asttm include shrinkage or expansion due to hydration, settlement, evaporation, and other physical and chemical effects. However, the specimen used in this test method is not completely unrestrained so that the measurements are primarily useful for comparative purposes rather than as absolute values.

Further, the degree of aatm to which the specimen is subjected varies with the viscosity and degree of hardening of the mixture. It would be appropriate to use this test method as a basis for prescribing mixtures having restricted or specified volume change before the mixture becomes hard.
