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. Further, the degree of restraint to which the specimen is subjected varies with the viscosity and degree of hardening of the mixture.

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. 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. MSDS must accompany all samples submitted. Instructions Submit all necessary materials to perform test including mixing instructions, mix design.
These include shrinkage or expansion due to hydration, settlement, evaporation, and other physical and chemical effects. 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 c8827 will continue to fill the same space at time of hardening.
