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. However, the specimen used in this test method is not completely unrestrained so that the measurements are v827 useful for comparative purposes rather than as absolute values.

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 c82 reached. Instructions Submit all necessary materials to perform test including mixing instructions, mix design. 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 notes and footnotes shall not be considered as requirements of the test method. Results Produced All height change measurements will be reported as percent change over time.
Further, the degree of restraint to which the specimen is subjected varies with the viscosity and degree of hardening of the mixture. Historical Version s – view previous versions of standard.

Time for Results Please contact a CTLGroup chemical services representative or Project Manager to discuss your individual project needs and testing response times. Atsm to Active This link will always route to the current Active version of the standard.
The values stated in each system may not be exact equivalents; therefore, each system shall be used independently of the other.
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. Referenced Documents purchase separately The documents listed below are referenced within the subject standard but are not provided as part of the standard.
Combining values from the two systems may result in non-conformance with the standard. These include qstm or expansion due to hydration, settlement, evaporation, and other physical and chemical effects.
