Historical Version s – view previous versions of standard. If you need more info qstm have any questions, please note the Lab ID number and contact us at:. 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.

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. Combining values from the two systems may result in non-conformance with the standard. 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.
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 freshly mixed cementitious mixture that will continue to fill the same space at time of hardening.

These include shrinkage or expansion due to hydration, settlement, evaporation, and other physical and chemical effects.
MSDS must accompany all samples submitted. It c8227 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. 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.
