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. 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.

These notes and footnotes shall not be considered as requirements of the test method. 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.
Results Produced All height change measurements will be reported as percent change over time. 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.
Time for Results Please contact a CTLGroup chemical services representative or Project Manager to discuss your individual project needs and testing response times.
These include shrinkage or expansion due to hydration, settlement, evaporation, and other physical and chemical effects. MSDS must accompany all samples submitted. The values stated in each system may not be exact equivalents; therefore, each system shall be used independently of the other.
