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. Contact Mike Morrison for additional information. Referenced Documents purchase separately The documents listed below are referenced within the subject standard but are not provided as part of the standard.
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. Further, the degree of restraint to which the specimen is subjected varies with the viscosity and degree of hardening of the mixture.

Asm for Results Please contact a CTLGroup chemical services representative or Project Manager to discuss your individual project needs and testing response times. The values stated in each system may not be exact equivalents; therefore, each system shall be used independently of the other. 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.
ASTM C827/C827M – 16
Print and complete the following order ast. 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 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.
