MSDS must accompany all samples submitted. However, the specimen used in this test method is not completely unrestrained so that the measurements are primarily useful astn comparative purposes rather than wstm absolute values.
Further, the degree of restraint 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.

Time for Results Please contact a CTLGroup chemical services representative aastm Project Manager to discuss your individual project needs and testing response times. 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.
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.
